[SOLVED] Unable to install PG gem on Fedora 17

Issue

The pg gem is being stubborn so I can't load my app on new computer. Seems like multiple problems, not being able to locate pg_config and then extconf.rb

#psql working...
psql (9.2.1)
Type "help" for help.

nd =>
\q

$ pg_config:

#adding the path to bashrc...
$ nano .bashrc

PATH=/usr/pgsql-9.2/bin:$PATH

#seems to work...
pg_config: /usr/pgsql-9.2/bin/pg_config

$ sudo gem install pg

#but i get the same errors...
Building native extensions.  This could take a while...
.......
ERROR:  Error installing pg:
        ERROR: Failed to build gem native extension.

        /usr/bin/ruby extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

any linux people out there that have dealt with this problem?

Solution

this is solved with

$ yum install /usr/include/libpq-fe.h
