Hi every:
I'm trying to install postgres gem but since I have latest postgres
version then some problems appears. When I run gem install postgres I
get this:

    An error occured while installing pg (0.13.2), and Bundler cannot continue.
    Make sure that `gem install pg -v '0.13.2'` succeeds before bundling.

    This is the correct gem? pg? Any other help on get RoR and PostgreSQL up
    and running?

    So what's unclear about that? If you believe the required files are

    The problem is just one: doesn't work even if I provide correct paths to
    gem installer. See below:

    [root@ruby-devserver yum.repos.d]# locate libpq-fe.h
    /usr/pgsql-9.1/include/libpq-fe.h

    So it's installed!!! :D

    This time you left off the additional '--' after `gem install pg` - you had

    Just go one step at a time. Here's *exactly* what works on my Mac:

    gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config

    You should be able to just substitute the appropriate location for
    your own pg_config file.

    gem install pg -- --with-pg-include=... --with-pg-lib=...

    Note the double dashes...

    Looking at "gem help install" would have helped you.

    Does that path end with a file named 'pg_config'? No. It does not.
    So, again, nothing like the example I gave you.

    Ok, sorry I found the directory in another place so all the time I was
    wrong thinking in config files and because of that I use
    /var/lib/pgsql/9.1/data and not /usr/pgsql-9.1/bin/pg_config as should
    be from the beginning. So aplogies once more time :-(

    What's unclear about it is that it doesn't fucking work.

    Been there, done that, the error message and instructions are incorrect; providing the path to pg_config does not work, even when the postgres install is completely default with everything in the standard location. It's a bit frustrating that I can't find my notes right now, but basically nearly all the results from google searches are really bad advice, and what is required is to use the option that specifies the root of the postgres install.

    If there is a reproduceable bug in core Postgres, please show me here
    so I can resolve it.
