At SciPy2011 a few of us managed to convince Andreas Klöckner to
bundle the necessary bits of boost with PyCUDA so as to remove a
dependency and grow the user-base. I recall this causing trouble for
some segment of his users that had boost installed on the system, but
I don't know the details.
Andreas (CCed): Do you remember what problems those were? Fred B. told
me about it over lunch one day but I can't recall what exactly went
