I will give that a try.
Though knowing what the problem is I wonder if another solution is to
make the plpythonu lib layout follow the description of the 2/3 split
detailed here:
http://www.postgresql.org/docs/9.2/static/plpython-python23.html
In particular:
"The language named plpythonu implements PL/Python based on the default
Python language variant, which is currently Python 2"
In other words automatically create a symlink:
plpython.so -> plpython2.so*
