Hi,

During a test rebuild of HDF5's reverse dependcies against HDF5 2.1.0
currently in experimental, xmds2 FTBFS with:

Checking for program 'h5cc'                           : /usr/bin/h5cc

AttributeError: 'NoneType' object has no attribute 'group'

I tried to poke into the xpdeint/support/wscript file; but while xmds2 seems
to build successfully many tests fail then. So I let it to the maintainer of
the package :)

Don't hesitate to reach if needed, as I am in touch with HDF5 devs and
they are willing to help.

Best,
_g.
