Comment(by psychicpsquirrel@…):

 I was having a similar problem to the above, and found a fix on a blog
 post that worked for me. In addition to the
 {{{
 ERROR! MySQL manager or server PID file could not be found!
 }}}
 error message, I was also getting this error in the console.
 {{{
 18/06/11 12:07:10 AM com.apple.launchd[1] (0x10e4b0.nohup[2213]) Could not
 setup Mach task special port 9: (os/kern) no access
 }}}
 While searching for this second error message, I found this blog entry
 that said that the second error message was caused by a problem with the
 permissions on the /opt/local/var/db/mysql5/ directory. I found a couple
 of files that had the owner set to root:admin instead of _mysql:admin. All
 I did was
 {{{
 sudo chown -R _mysql:admin /opt/local/var/db/mysql5/
 }}}
 and I was able to start mysql from the command line, and with launchctl.

 This might not exactly what the others here are experiencing, but it's
 worth a try. Here's a link to the blog post.
