php4-mysql-4.4.6 overrides *MYSQL* variables?

[Harlan Stenn]

I have been noticing that when I run 'portupgrade -Ppa' (or reasonable
variants thereof) on a system that contains:

 /etc/make.conf:
 ...
 DEFAULT_MYSQL_VER=      41
 WANT_MYSQL_VER=         41
 WITH_MYSQL_VER=         41

(I used to just use DEFAULT_MYSQL_VER=41 and that didn't seem to be
enough.)

Anyway, when I run portupgrade it seems that php4-mysql-4.4.6 goes ahead
and installs mysql-client-5.0.37 even though mysql-client-4.1.22 has
already been installed (and is the version I want to use).

Ideas?
