>Description:
Mac OS X Server comes with mysql4 built in. It would be nice to 
PREFER_NATIVE=mysql-client (of course with MYSQL_VERSION_DEFAULT=41).
>How-To-Repeat:

>Fix:
Patch in <http://www.ascia.fi/~jml/pkgsrc/darwin/mysql4-client-builtin.diff> 
adds builtin.mk to mysql4-client. I don't think anything depends on 
mysql4-server.
