Re: plpython module import errors

Now, I found that python version postresql is using is 2.6 and path to it is
"['/home/apy/rrun/build/activepython-svn-trunk/build/py2_6_4-linux-x86-apy26-rrun/CoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIx/lib/python26.zip', '/home/apy/rrun/build/activepython-svn-trunk/build/py2_6_4-linux-x86-apy26-rrun/CoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIx/lib/python2.6/', '/home/apy/rrun/build/activepython-svn-trunk/build/py2_6_4-linux-x86-apy26-rrun/CoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIx/lib/python2.6/plat-linux2', '/home/apy/rrun/build/activepython-svn-trunk/build/py2_6_4-linux-x86-apy26-rrun/CoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIx/lib/python2.6/lib-tk', '/home/apy/rrun/build/activepython-svn-trunk/build/py2_6_4-linux-x86-apy26-rrun/CoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIx/lib/python2.6/lib-old', '/home/apy/rrun/build/activepython-svn-trunk/build/py2_6_4-linux-x86-apy26-rrun/CoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIxCoReAcTiVePyThOnPrEfIx/lib/lib-dynload']"

what this means? It seems that this path is of the python installation which is used to compile default plpython.so.
If I will compile the source with python 2.7, and change the old plpython.so with new, will my problem solved?
Thanks and regards,

It can only compile against one and by default that will be the 'system ' version. To determine what that is , at the system command line enter:

python -V

If you want to compile against 3.2 you will have to tell Postgres that. See here for more detail:

http://www.postgresql.org/docs/9.0/interactive/install-procedure.html

PYTHON

Full path to the Python interpreter. This will be used to determine the dependencies for building PL/Python. Also, whether Python 2 or 3 is specified here (or otherwise implicitly chosen) determines which variant of the PL/Python language becomes available. See Section 42.1 for more information.
