Having issues installing gem ‘pg’ (postgresql)?

If you run into the “Can’t find the ‘libpq-fe.h header” error, see below if you want to know how I solved the problem:

Installing pg (0.15.1) 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /home/myhomedir/.rvm/rubies/ruby-1.9.3-p392/bin/ruby extconf.rb 
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
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.

Provided configuration options:

Gem files will remain installed in /home/myhomedir/.rvm/gems/ruby-1.9.3-p392@yourapp/gems/pg-0.15.1 for inspection.
Results logged to /home/myhomedir/.rvm/gems/ruby-1.9.3-p392@yourapp/gems/pg-0.15.1/ext/gem_make.out

An error occurred while installing pg (0.15.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.15.1'` succeeds before bundling.

I was able to solve the problem by executing the following before doing a ‘bundle install’:

sudo aptitude install libpq-dev
