help needed with python package for mxe-octave

[John W. Eaton]

I'm trying to update the version of osmesa we use in mxe-octave.

Building is failing with

/scratch/jwe/mxe-octave/default/w32/usr/bin/python 
src/mesa/main/format_pack.py src/mesa/main/formats.csv > 
build/windows-x86-debug/mesa/main/format_pack.c
Traceback (most recent call last):
  File "src/mesa/main/format_pack.py", line 2, in <module>
    from mako.template import Template
ImportError: No module named mako.template
scons: *** [build/windows-x86-debug/mesa/main/format_pack.c] Error 1
scons: building terminated because of errors.
/scratch/jwe/mxe-octave/default/w32/Makefile:835: recipe for target 
'build-only-osmesa' failed
make[1]: *** [build-only-osmesa] Error 2
make[1]: Leaving directory '/scratch/jwe/mxe-octave/default/w32'

Note we are building a copy of Python for use during the build and it's 
missing this package that is now required to build osmesa.  What's the 
right way to build this package for the version of Python we are using?

Thanks,
