Thanks Eliot. I did your idea and I could make progress. Then I have the
errors that John said...so I am trying to compile the StackVM. Now, the
error I have is:

Build Croquet of project CoreVM with configuration Development

Ld build/Development/Croquet.app/Contents/MacOS/Croquet normal i386
cd /Users/mariano/PhD/Marea/usedBit/CogVM/Cog/macbuildStackVM
/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

ld: duplicate symbol _warning in
collect2: ld returned 1 exit status
Command /Developer/usr/bin/gcc-4.2 failed with exit code 1

I don't understand if the error is the "duplicate symbol _warning " or if
there is really another error (I am a C newbie).

thanks in advance for any help
