Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary

Gem files will remain installed in /home/aditya/.rvm/gems/ruby-2.1.3/gems/pg-0.17.1 for inspection.
Results logged to /home/aditya/.rvm/gems/ruby-2.1.3/extensions/x86_64-linux/2.1.0/pg-0.17.1/gem_make.out
An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

My current version of Postgre is 9.3.4

Please suggest I tried other answer but i can't find answer. I tried to run other commands

bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config  

But I got error

pg: bundle: No such file or directory
pg: config: Is a directory                                                     
pg: build.pg: No such file or directory

I tried solutions of Can't find the 'libpq-fe.h header when trying to install pg gem but its not solving my problem
