Mysql – Ruby EE ./installer fails on thesql gem installation

MySQLruby-enterprise-edition

So, installing Ruby Enterprise Edition went fairly smoothly (except for a very odd quirk of the system I'm on, where I had to apt-get install build-essentials because there was no GCC…), but it failed to install any of the database gems properly. I mainly want to use MySQL. Here's the output of Ruby EE's ./installer during the mysql gem installation:

Apparently my server's MySQL installation didn't come with source, so I can't just recompile and hope it works… I tried to download the version and compile that, but I'm not sure what to do from here. Any ideas? MySQL is already running on this server with quite a few databases, so I'd also rather not mess with what's already here…

After a fair bit of struggle, I started browsing through aptitude hoping to find a package that might solve the problem. I found libmysqlclient-dev, installed it, and rebuilt the gem... and it worked. I feel pretty stupid, heh, but this is only my first time trying to deploy a Rails app to a real webserver.
