[C++-sig] Boost.Python Quickstart test failure/segfault on Boost 1.35.0 Python 2.5 on 64-bit Linux (RedHat)

[Eric Newhuis]

This appears to be a result of using Python 2.55  built from pkgsrc.  I 
don't have this problem when I  download and build Python "by hand".

I'll take this up with the pkgsrc maintainers.
