rb-mysql compile error

[Mark Duling]

Yes, they were merged, but the problem doesn't have to do with the merge. 
The merged port was fine until mysql5.0.24, but was broken by 5.0.24a.

The problem was supposed to be fixed by mysql 5.0.26, but the error
morphed into the one you are experiencing and I don't know yet what the
fix will be.  It should probably be reported to the mysql folks.
