no, the problem is not the compiler.
it's the headers that are used.

according to the documentation of CGL and according to the header-files
(on a 10.5 machine), the definition of the function is:
> "CGLGetVirtualScreen(CGLContextObj ctx, GLint *screen)"
> and not "long int*"

(quoting my other email from beginning of november).

the header file
(/System/Library/Frameworks/OpenGL.framework/Headers/OpenGL.h) on the
build-machine has:
extern CGLError CGLGetVirtualScreen(CGLContextObj ctx, long *screen);


i _strongly_ believe that you have installed the wrong headers.
if you could show me _any_ "official" ressource that uses "long" i might
be convinced.

in the meantime i have added some hackz to the Gem code that should make
it compile again.

the svn client installed on the build-machine (/sw/bin/svn) is somewhat
outdated (1.4.4) and refuses to "svn update" the sandbox.
