Much better. That's what I ended up with.

True, it's not MacPorts' fault. Nor is it my fault. It's not practical  
to safely avoid .mp for the beginnings of all things. Users can create  
imap mail boxes and name them what they like.

I just want to safely remove a slug of files that MacPorts put on my  
system and then forgot about. Those files are there because at times  
it's been the only way to get things installed/upgraded using  
MacPorts. I'm happy that MacPorts didn't just clobber them but at some  
point I think I want these removed from places like $prefix/bin/*.mp*.  
I'm just looking for an easy and safe way to do this and find -name  
*.mp* rm scares me. It's easy but not safe.

Restoring from a backup is a terrible solution. I make nightly backups  
of my databases but loosing a days worth of data will make me very  
Likewise losing all the emails in an imap mailbox would make me  
equally unpopular. I think for me it's best to just move user data  
outside /opt/local. I already moved it all to a subdir of /opt/local/ 
var I should have just moved it outside /opt/local altogether and I  
wouldn't be worried about find $prefix -exec rm commands.
