Installing RoR gem mysql throws error

[FreshFocus]

I'm trying to do some investigation to help out my host (expeditite).

RoR is installed and I've tried to install the mysql(2.7.3) gem via the RubyGems portion of cpanel. I did a "search" from that page, chose "mysql(2.7.3)" and install. It throws this error:

Any idea why it's throwing this error? I'm trying to install Tracks and am stopped at this portion of the install. Might I add that I've done a fair bit of Googling on this issue. It seems that it can be installed with the

sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

shell command but I am told that since this is tied into cPanel that it cannot be installed in this manner unless I was on a dedicated host, which I am not.

Any assistance that you can give is greatly appreciated.

Try the following;

su - USERNAME

Make sure gcc works
gcc

gem list --local <--Show what is installed for this user (probably nothing that's why there is a problem)
gem install mongrel <-- install required
gem list --local <-- ensure they installed
gem install actionmailer <-- test a common gem module
gem install mysql <-- install mysql - No options required
gem list --local <-- verified installed

Test application
