plpythonu on 7.4
On a 7.4 installation built --with-python...
Python installed is 2.3.4.
On createlang, I get the following error:
createlang -U postgres 'plpythonu' template1
createlang: language installation failed: ERROR: could not load
library "/usr/local/pgsql74/lib/plpython.so":
/usr/local/pgsql74/lib/plpython.so: undefined symbol: PyDict_Copy
Anyone have any hints?
thanks,

What does "ldd /usr/local/pgsql74/lib/plpython.so" show?

Is this on fedora or redhat linux? If so a separate rpm must be installed for plpython to function.
If you built from source the config script must also include building python.

I'd bet on a python version issue, viz plpython expecting a newer
version of python than you have installed.

Hmmmm...Python 2.3.4 isn't very old, and the source code does contain
a PyDict_Copy() function. The only newer version is 2.4, and it
was released in late November. I was wondering if it was a dynamic
linking issue, like plpython.so not finding libpython*.
Does PostgreSQL's configure script check versions for Perl, Python,
Tcl, etc.? If the version matters then configure ought to complain
about it.
