MySQL update

[Glenn McCalley]

Trying to update MySQL from 4.1 to 5.5.
Updating mysql-client first.
Make works great, but make install refuses to install saying 5.5 conflicts 
with 4.1, run
pkg_delete for 4.1.
pkg_delete for 4.1 refuses to deinstall as all the php52 packages 
(extensions, mysql, mysqli, pdo_mysql etc.) depend on mysql 4.1.

Question:  Do I have to deinstall everything, and then put it all back 
together, or can I force the mysql 5.5 client and 5.5 server to install?

Thanks!
Glenn.
