Fresh install + updatemsf = fail

[Primux]

Hello everyone. Let me start off by saying it's been quite some time since I've used backtrack (I think 3 was the last stable version I'd used) so I'm a bit behind. I was going to post this in the beginner's section, ut the sticky in that section indicated this kind of question should go here.
At this point I've tried this a few different times & ways, just reverting to a snapshot on my VM of a fresh install upon failure, but that's failing me, SO. . .

I've got a fresh install of BT5/Gnome. Metasploit works, things are nice. Of course metasploit is outdated, so I try to run msfupdate and it updates fine. I load msfconsole and try to use db_driver and it says it's an unknown command. That happened to me before, but from experience I knew that db_connect was still recognized. Tried that and I got "No Database Driver installed try gem install pg. Which of course I tried. That gave me an error saying it couldn't find libpq-fe.h. The file is there. Checked pg_config.bin which the ./configure said it was using & it lists INCLUDEDIR as /opt/framework3/postgresql/include/ and the file is in there. This makes no sense to me.

No I can't think of anything else. All help is appreciated. Thanks in advance.

UPDATE: Got the issue with ruby fixed, not sure exactly how as I installed a ton of stuff, but now the problem is when I try

gem install pg

I get an error telling me that it can't find libpq-fe.h BUT that's only when I run it from metasploit. If I run it directly from the command line it works fine.

Any ideas? Google's shooting me in all kinds of directions, none of which actually cover my problem.

I solved with an apt-get install libpq-dev
