I've never seen problems with different python version types, nor
heard of different unicode widths on Windows.
pandas is compiled against numpy 1.6 and is ABI incompatible with numpy 1.5
I never managed to install a sklearn binary and I don't know which
numpy they are built against.
cvxopt build script requires python 2.7, and the Gohlke binaries
require the mkl build of numpy.
but most of the time it just works, especially when I'm not using an
outdated python 2.5 or 2.6 and numpy 1.5.
