Seems to have some potential but a few comments to the developer:
If you're going to have a package installer for a small app like this, at least give it the ability to install the app where the user wants - some of us only like to keep Apple apps in /Applications. A better solution would be to roll all resources into the app itself and just distribute it in a zip or dmg.
Some explanation of the FreeType framework would be appreciated, either within the installer or at the very least, on the app's web page.
A postflight script which launches the app without warning is very disconcerting and smacks of malware. Most of us don't mind double-clicking when WE'RE ready to run an app.
