[Debian-med-packaging] Bug#750845: python-biopython: FTBFS on non-X86 due to missing build-dep raxml

[Scott Kitterman]

Source: python-biopython
Version: 1.63+dfsg-5
Severity: serious
Justification: fails to build from source (but built successfully in the past)

python-biopython either needs to limit itself to being built on X86
architectures or built without raxml on the other archs.  I did not check
if the latter was feasible or not.  This has blocked transition to testing
for a month now.  It also blocks completion of the rebuilds for dropping
python3.3 support.
