Can't install gem ruby-pg

I’m running ruby 1.9.1 and need a gem sitting here:

I do:

[root@www admin]# gem install maxime-ruby-pg-for-ruby-1.9.1rc2
ERROR: could not find gem maxime-ruby-pg-for-ruby-1.9.1rc2 locally or
in a repository
[root@www admin]#

my sources are:

[root@www admin]# gem sources
*** CURRENT SOURCES ***

http://gems.rubyforge.org/

Driving me crazy

GitHub - maxime/ruby-pg-for-ruby-1.9.1rc2: this is just a hacked version of ruby-pg that compiles with ruby 1.9.1rc2

I do:

[root@www admin]# gem install maxime-ruby-pg-for-ruby-1.9.1rc2
