The problem was RPy1 -- they didn't play nicely together. Once I removed
RPy1, things were fine.

That raises the question, what we should do with the RPy1 dependent
code? Per, could you port ithe rest to RPy2 as well (possibly removing ENET, if
it is fully replaced by GLMNET now)?


Sidenote: If refactored the glmnet tests a bit and included them into
the main battery. That revealed a few problems that I am addressing
right now -- will push what I have now nevertheless and push the fixes
later on.

Thanks,

Michael
