I am not using the xcode IDE for the Mac OS port, but a makefile
Packages I installed through fink are: allegro4 theora0 vorbis0 ogg dumb freetype2-dev . I had to fiddle around with dumb sources so that it would build aldumb (Allegro support).
Also I only have Snow Leopard and xcode 3.2.6 with iOS SDK 4.3 (or something) because that is the latest one available for that without paying teh big bux. I don't really think that matters though.
What I am doing right now is cross-compiling libraries, which is a lot of fun because of interesting syntactical differences between the Apple tools and GCC (like "__asm__" vs. "asm" :
). Also the Apple assembler is some outdated version of the gcc assembler, joy.
