Short answer: you can't.

Long answer: you might but the devs are not going to help you

Huge answer: a mysql client has support for connecting to a server on 
localhost. Apps like dovecot etc therefore assume the same. So the ebuilds 
install mysql if you ask for mysql support and you get everything.

There is no exact meaning for the mysql USE flag, it is interpreted (mostly) 
in whatever way the dev thinks it makes sense. Maybe this should not be like 
this. Doesn't matter - right now that's how it is. So you could inspect each 
ebuild you use for stuff that has mysql support and rip it apaprt to make it 
do what you want. Repeat for every version bump.



Or, you could just do the sane thing:

# equery size mysql
 * dev-db/mysql-5.1.46
         Total files : 403
         Total size  : 45.03 MiB
 
It's 45M, not a train smash. Most of that is docs, support configs, other 
weird shit that Sun thought was a good idea, client libs, common libs. And the 
server binary.


You are running php, dovecot and postfix on the box. Therefore apache too.

Trust me, the extra 2M the mysql server takes up is not disk space you are 
short off. Not worth the effort.
