Greetings,
After building postgresql from the git repository, I've tried to create a db that I have, and I've faced the exact same problem described here: http://archives.postgresql.org/pgsql-general/2012-02/msg00753.php
Basically, the extension directory does not contain plpythonu.control. I've build with gmake world and installed accordingly.
The relevant bug seems to have been marked as fixed by Devrim. Am I missing something here?
Best regards
Seref
