Pg gem with Ubuntu

I am trying to install pg gem with a new rails application, but I still get the same error:

Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension. /home/arthur/.rvm/rubies/ruby-1.9.2-p320/bin/ruby extconf.rb --with-pg-lib=/usr/lib checking for pg_config... yes Using config values from /usr/bin/pg_config checking for libpq-fe.h... yes checking for libpq/libpq-fs.h... yes checking for pg_config_manual.h... yes checking for PQconnectdb() in -lpq... no checking for PQconnectdb() in -llibpq... no checking for PQconnectdb() in -lms/libpq... no Can't find the PostgreSQL client library (libpq) *** 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.

I already tried all of this question: How to install pg gem PostgreSQL on Ubuntu? but nothing worked for me.

That Ruby 1.9.2 and Rails 3.2, by the way.

thanks

Install postgresql 9 and then install your stone.
