[gambit-list] Gambit and

All --

I'm trying Gambit for the first time on my OS X Snow Leopard machine with XCode 3.2 and I'm getting errors (can't find limits.h). If I set GAMBC_CC_VERBOSE=yes, the command line for gcc is the following:

gcc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -no-cpp-

precomp -Wno-unused -O1 -fno-math-errno -fschedule-insns2 -fno- trapping-math -fno-strict-aliasing -fwrapv -fomit-frame-pointer -fPIC - fno-common -mieee-fp -I"/Library/Gambit-C/v4.5.2/include" -c -o "foo.o" foo.c

The problem (I guess) is that the listed SDK isn't installed. Any way I can specify a different one? Here are the ones installed:

ls /Developer/SDKs/

MacOSX10.5.sdk MacOSX10.6.sdk

Thanks,

Ted C.
