Well, as the original developer of that library I would like to make =
some comments
to your questions.

A recompilation is quite simple. On Windows you need Visual C (I prefer =
version 6
as version 7 with .Net adds all sorts of dependencies to your Windows =
installation.
There is one single variable which defines to which Python DLL the =
LabPython code
should be dynamically linked to on loading. In fact the LabPython DLL =
even has a
mechanisme to link dynamically to another Python DLL through calling a =
specific VI,
however this mechanisme hasn't been tested throughly and not at all on =
Linux
(I believe I couldn't get it work as intended there, as I don't =
understand shared
library relinking as well under Linux then I do under Windows) so not =
sure if it
could even work for you. Also this assumes that Python didn't do any =
binary API
changes between 2.2(.1) and 2.3. If they did it would likely require =
some changes
to the LabPython library itself.

I haven't had the need to do anything with it lately and support from =
other
users has been minimal. If you know how to use a C compiler to do at =
least a
correct recompilation there should be no real problem. Otherwise my time =
is
at the moment very limited so I won't be able to do many modification =
and even
less to extensively test and debug any of them.
