Interesting -- mine are:

$ otool -L  /opt/local/lib/libfreetype.dylib
	/opt/local/lib/libfreetype.6.dylib (compatibility version 11.0.0, 
current version 11.0.0)
	/opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current 
version 1.2.5)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 111.1.5)

so none of the CoreServices stuff - maybe a 10.4 vs. 1.5 difference.

nice work!

those look reasonable.

I'm not sure what the deal is with this -- there are issue with 
different TK versions, but I dont us TK, so I'mve never figured that out.

In theory, yes.

Please put them on a publicly accessible site if you can, and sent a 
note tho these lists asking for testing. If you don't have anywhere to 
put them, you can open a Dropbox account, or soemthing else, or send 
them to me and I'll put them on mine.

I suppose dmg is a little better, but either one is fine.

Thanks for all this work!
