Thanks for the explanation Igor. I tried now to exlcude gcc3x-inter.c and
use interp.c or vice-versa, but in any case I have the error:
Build Croquet of project CoreVM with configuration Development
Ld build/Development/Croquet.app/Contents/MacOS/Croquet normal i386
setenv MACOSX_DEPLOYMENT_TARGET 10.5
/Developer/usr/bin/gcc-4.2 -arch i386 -isysroot
-mmacosx-version-min=10.5 -framework CoreFoundation -framework Carbon
-framework OpenGL -framework AGL -framework QuickTime -framework CoreAudio
-framework AudioToolbox -framework IOKit -framework Foundation -framework
SystemConfiguration -framework AppKit -prebind -o
"_dumpPrimTraceLog", referenced from:
_error in sqMacMain.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
So....I will continue trying to see what the problem is.

excelent. Thanks for the explanations :)
