I was citing that behavior from memory. It actually builds/installs OK until
one decides to add the handler to a database:

$ createlang plpythonu
createlang: language installation failed: ERROR:  could not load library
"/usr/local/lib/postgresql/plpython.so": dlopen
'/usr/local/lib/postgresql/plpython.so' failed.
(/usr/local/lib/python2.4/config/libpython2.4.so: Undefined symbol
"pthread_attr_destroy")

If I build the backend with the pthread stuff, this step succeeds.


Thanks,
