Just like the error message says, we need to see the details in
config.log for why this particular test failed to find the Octave header
files or libraries.

Actually I would recommend going to the development branch of Octave for
use with pytave. So if it's possible to build Octave from an hg clone in
the msys environment, that would be best. Second best would be running
'make dist' of a development version of Octave on a GNU/Linux system,
copying the tarball over to Windows, and building from the source
distribution in the msys environment.

Tatsuro, have you successfully built Octave's default branch in msys?

Thanks for the details on setting this up.
