[Debian-med-packaging] Bug#746624: python-biopython: FTBFS - t_coffee needs HOME or TMP

[Aaron M. Ucko]

Source: python-biopython
Version: 1.63+dfsg-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Builds of python-biopython on the autobuilders, which decline to
provide home directories, have been failing:

  ApplicationError: Command 't_coffee -infile Fasta/fa01' returned non-zero exit status 135, '--ERROR:  : Could not set a HOME directory.Set any of the following environement variables to some suitable location: HOME, HOME_4_TCOFFEE, TMP or TEMP [FATAL:T-COFFEE]'

and likewise for the other two t_coffee tests.  Please arrange to
point one of those variables to a temporary directory in the build
tree.

Thanks!
