pkg or version conflict problems

[JK]

I'm afraid that through my moronic attempts over the last few months I 
have gotten my 5.1 system into bad shape.  While trying to clean it up 
and make some sense out of it I've been trying to build mysql.  I'm 
getting this error message and no matter what I try I cannot get past 
it.

root at mysys:/usr/ports/databases/mysql50-server# make WITH_OPENSSL=yes
===>  mysql-server-5.0.17 is marked as broken: MySQL versions 
mismatch: mysql41-client is installed and wanted version is 
mysql50-client.

pkg_info doesn't show any mysql's installed.  I've tried pkg_delete 
and pkg_deinstall's. I've gone into all the 
/usr/ports/databases/mysql* directories and done make deinstall

Can someone please tell me what's wrong and how to fix it ( and maybe 
how I got into this state so I can understand what's going on)?

There must be another database or more involved that I'm not 
understanding.

Thank you
