[Debian-med-packaging] Bug#751277: python-biopython: FTBFS on mips* powerpc s390x

[Michiel de Hoon]

Hi Andreas,

I was able to replicate this bug on a PowerPC with Python 2.7, but only if I replace the single character into a single unicode character
(e.g. in line 212 of test_Cluster.py, if I replace method='a' by method=u'a').
Can you confirm that you get this bug with Python 2.7 even with simple strings rather than unicode?

Thanks,
-Michiel.

 It seems after having fixed
 the issue caused by wise we have one
 remaining problem:
 
   On powerpc[1] and s390x[2] test_Cluster
 fails even with Python 2.7 with:

 On sparc[3]
 there is a problem with dialign but sparc is no release
 architecture and wie might ignore this.  It
 might be a helpful hint
 anyway.
 
 Any hint for the test_Cluster
 problem?  If not I would also consider to
 hide it cowardly under the carpet for the
 moment.  The new package is so
 much better
 tested than the one in the testing distribution which
 does
 not even dare about any unit tests and
 only for this reason reached the
 testing
 distribution.
 
 What do you
 think?
 
 Kind regards
 
    
    Andreas.
