Package: python-scipy
Version: 0.10.1+dfsg1-3
Severity: serious
Justification: fails to build from source (but built successfully in the past)
Please see attached a somewhat minimalistic code to reproduce the
problem.
it fails only on s390x -- fine on s390 and any other architecture/port where
pymvpa2 was just built.
