I tried to install ROOT 5.12 on mac
with gcc
gcc -v
Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5026.obj~19/src/configure --disable-checking --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^+.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/gcc/darwin/4.0/c++ --build=powerpc-apple-darwin8 --host=powerpc-apple-darwin8 --target=powerpc-apple-darwin8
Thread model: posix
gcc version 4.0.0 (Apple Computer, Inc. build 5026)
I did
cvs -d :pserver:cvs@root.cern.ch:/user/cvs co -r v5-12-00 root
cd root
./configure --build=debug --enable-qt --enable-table --disable-cern --disable-python
make
I got

What I did wrong 
?
Thank you.
