Here's an odd problem installing DBD:Pg. Usual steps (have done this module a few times now) ...

got prerequisites in place
got it built
set up postgres and installed a testdb called pgtest
checked I can access pgtest
set the env variables

The problem I got is "no such file" - it seems that somehow the driver is looking for the wrong named socket ... :


admin@li8-246:~/.cpanplus/5.8.8/build/DBD-Pg-1.49$ perl -Ilib t/01connect.t
1..8
Bail out! Could not connect: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

As you can see, the driver is looking for a socket with a different name to the one that actualy exists. What could cause this? I have tried make clean and a rebuild, also restarting postgresql itself. I can connect to the db just fine from the command line too.
