[Stackless] "ImportError: No module named stackless" after installation on Ubuntu

Well, that is very odd. I'm on a regular i386 linux machine, not some 
weird CPU architecture.

Actually, there was no stackless.h at all in the tarball of 2.7

wget http://www.stackless.com/binaries/stackless-27-export.tar.bz2
tar -jtf stackless-27-export.tar.bz2 | grep stackless.h
-> returns nothing

I've tried it again with 2.65, even if I edit stackless.h so that 
STACKLESS is always defined, I'm still getting that ImportError.
