Trouble installing pg gem on OSX 10.10

I'm trying to install the pg gem on my system (macbook pro running 10.10, Postgresql 9.3.5_1, Ruby 1.9.3p547, Xcode v6.1 (6A1052c)) with this command:

ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-config=/usr/local/Cellar/postgresql/9.3.5_1/bin/pg_config

Returns this:

Building native extensions with: '--with-pg-config=/usr/local/Cellar/postgresql/9.3.5_1/bin/pg_config'
This could take a while...
ERROR:  Error installing pg:

What?

I'm pretty sure I have the developer tools installed:

xcode-select --print-path

Returns:

/Applications/Xcode.app/Contents/Developer

My mkmf.log file contains this:

checked program was:
/* begin */
1: #include "ruby.h"
2:
3: int main(int argc, char **argv)

6: }
/* end */

Doesn anyone have a clue about what's going on here? Any help would be greatly appreciated!

This solved my problem

First you should download the Postgres App (http://postgresapp.com/) and place it in your Applications folder. Extract and open it, now write this in your console.

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

I wrote 9.4 because it was my latest version.

I finally solved this by ripping out all my rubies thus: rvm implode. Then I reinstalled rvm and Ruby 2.1.3 instead of 1.9.3. Sadly, I don't know exactly what the cause of the problem was, but I'm suspecting Ruby 1.9.3 does not install nicely with rvm on OSX 10.10.
