OK, doing better now:
'gcc' is not recognized as an internal or external command,
operable program or batch file.

I see in
http://lists.alioth.debian.org/pipermail/pkg-exppsy-pymvpa/2009q2/000495.html
that parameter selection is not generated/optimized; so what SVM
should I test to auto generate optimized classifier(s)?
