Patch from Gaudenz Steinlin <gaudenz@debian.org>
Debian bug: #552014
Reported upstream: https://svn.boost.org/trac/boost/ticket/3544
Fixed upstream: 2010-02-28 (post Boost 1.42)

Add --xpythonid parameter to the build system to only add an identification 
to Python libraries. The existing --buildid parameter adds an id to all 
libraries and leads to uneccessary duplication of libraries if only the 
Python version for the build is different.
