It should not, as long as it is a Python 2.6.x release.

This is however a big issue. I don't know how to solve it without some
Python black magic.

With the attached patch configure.py asks Python directly for a module
called elyxer. It was submitted to lyx-devel but I'm not sure if it
was accepted.

In fact the -tt flag was not necessary; what did the trick was calling:
  python elyxer.py
instead of simply using elyxer.py as an executable file:
  elyxer.py

It should, although installing without admin privileges can be a problem.
