Sounds good.  I switched to the gnu-build-system + autotools.  This also
made the "install" phase somewhat easier.

The tool "pump.py" is distributed with the Googletest source.  It
appears to be a part of the source rather than a bundeled dependency and
the only reference to it that I found was in Googletest, so I would
assume it is a part of Googletest.  Therefore I did not create a
seperate package for that, but used the one provided in the Googletest
source tree.  With that, the pre-generated headers can be reproduced.
The attached patch does that.

Thank you!
