ARR MIHARDIES  From your error message, am I correct in understanding that you are running on a non-english installation of OS X?  
(Version 20081218)

TIKILAB  Nope, I am running US English, freshly installed a few weeks ago.  
(Version 20081218)

ARR MIHARDIES  Have any previous versions worked for you? Have you tried re-downloading the program?

I asked if you were running a non english version because I would be expecting the error message to read more like /usr/bin/perl instead of /usu/bon/nere . Sounds like a french system to me. Was the install for US/English or some other regional english selection?  
(Version 20081218)

ARR MIHARDIES  Try this.

Open up a terminal from your Applications/utilities folder.

type: "which perl"

and copy the line that is returned. It normally looks like /usr/bin/perl. But in your case might be /usu/bon/something

right (or control) click on the iDentify application and select show package contents. Brows to Contents/Resources and open appSettings.plist in a text editor like TextEdit.

scroll down to line 19 and 20, and you'll see this:

<key>ScriptInterpreter</key>

<string>/usr/bin/perl</string>

make sure that second line contains the text you just copied from the terminal. If it doesn't match, change it, then save the file and quit. Then try opening iDentify again.  
(Version 20081218)

TIKILAB  Hmm. I checked in the terminal and "which perl" returns "/usr/bin/perl". I checked inside the iDentify app bundle and AppSettings.plist says the same thing.

I also re-downloaded the app to make sure it wasn't corrupted. I tried dragging the included prefs onto the app. I made sure the app is in my "Applications" folder. I checked my International settings and they are all set to display english. Finally, I logged out of my account and tried it on a new user account. I got the same message each time.  
(Version 20081218)

TIKILAB  Oh, and I haven't previously run the program. This is the first time I've tried it.

I did notice that AtomicParsley is in the app bundle. I have previously tried a couple other programs that use AtomicParsley... maybe that has something to do with it?  
(Version 20081218)

ARR MIHARDIES  Having run other programs that use atomicParsley should not be an issue, as it is just a command line program. I wonder if this issue is 10.5.6 specific, as I am running on 10.5.5... I'll have to upgrade tonight to find out...  
(Version 20081218)

ARR MIHARDIES  Can you open a terminal and type "perl -v" and let me know what version of perl is on your system. 10.5.6 is running perl 5.8.8 I'm wondering if it got upgraded.. might be causing the problem.  
(Version 20081218)

ARR MIHARDIES  Well, I just upgraded to 10.5.6, and unfortunately, I am still not encountering your error.

Do you happen to know if your replaced or moved the pre-installed version of perl with a different one, or some such?

Oooh. another question... just hit me. What type of CPU is in your machine? Is is intel or PPC?  
(Version 20081218)

ARR MIHARDIES  Nevermind, I see the PPC bit in the original post. Don't know how I missed it. I looked through the entire threead twice before asking. I think I have fixed this issue for the next version though. I'll be labeling it as intel only here on macupdate. But I'd like you to give it a try on the ppc and let me know if it works.   
(Version 20081218)

TIKILAB  Yes, I am running perl 5.8.8 and it's a PPC.

I will be glad to try out a new version for you, but I am on vacation for the holidays and will only have access to this Mac until December 27, at which time I will fly home to my Intel Mac Pro. :)  
(Version 20081220.2)

ARR MIHARDIES  the new version went up today; give it a try.  
(Version 20081220.2)

TIKILAB  OK, progress. The program opened up, it correctly identified the TV show info, and Growl said it was completed. However, no tags were written.

I did it again and saw this error message after the show info:

sh: /Applications/iDentify.app/Contents/Resources/AtomicParsley: Bad CPU type in executable  
(Version 20081220.2)

ARR MIHARDIES  Strange. If I get info on the Atomic Parsley executable, it says it is Universal.. should work...  
(Version 20081220.2)

WCITYMIKE  I've got about 3000. (I use del.icio.us as a linklog for my blog, not an online bookmark service.) Works fine. So, not a numerical problem. :)
