Well, yes, apparently this is true.

My MySQL installation is 64 bit, and so as a result so are its 
libraries.

andrewo@host:/opt/mysql/mysql/lib> file libmysqlclient.so
libmysqlclient.so:      ELF 64-bit LSB dynamic lib AMD64 Version 1, 
dynamically linked, not stripped, no debugging information available

My Ruby installation is, indeed, a 32 bit install.  That's how the 
package I installed compiled it.  I tried changing that by recompiling 
in 64 bit mode early in this whole saga, but it was an absolute 
nightmare.  I don't think the make files of most of the Ruby libraries 
play nicely with 64 bit compile options.

I suppose I could install the libraries from a 32bit MySQL installation 
and rebuild the gem based on those...

Any other ideas?
