manually build mysql and sqlite3 gem for ruby?

[Thufir]

I was able to use mysql with ruby until updating, removing and re-
installing a few packages.  Now it's broken in what appears a chronic 
way.  Also, sqlite3 doesn't seem to install either.

Generally, this is a ruby problem.  However, I'm curious as to what the 
Ubuntu approach is.  I notice that more than a few gems are duplicated in 
apt-get.

Build the gems from source with make?

I've not found good, recent sources as to what the problem is nor the 
solution.
