after I update the Xcode project (and all subprojects) to use 10.6 sdk/GCC 4.2, I get the following error in texture.c and menu.c while compiling PeopsXGL: "error: 'glColorTableEXT' undeclared (first use in this function)"
i googled around and found a hack here: http://www.garagegames.com/community/forums/viewthread/115277/1
it appears that glColorTableEXT is deprecated in 10.6sdk.
adding the following to externals.h fixed the compile-time errors:
#define GL_COLOR_INDEX8_EXT 0x80E5
#define glColorTableEXT glColorTable
i haven't checked if it works properly though
I don't know if it's the proper place to put the code in.
If possible update the sources as you see fit, please.
