無法在Fedora 17上安裝PG gem

pg gem很頑固，所以我無法在新電腦上加載我的應用程序。好像多的問題，不能夠找到pg_config然後extconf.rb無法在Fedora 17上安裝PG gem

#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:

     /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.

任何Linux的人在那裏，已經處理了這個問題？
