Bugzilla Bug 156213

As [1] shows, the libwww ebuild was recently updated to use the new mysql
virtual. Unfortunately, no revision bump was introduced which rendered my
system in a state where i have 5.4.0-r7 installed, but virtual/mysql missing.

This is a problem when tetex checks for the existence for the virtuala and then
dies:
  Your libwww was compiled with MySQL but MySQL is missing from system.
  Please install MySQL or remerge libwww without mysql USE flag.
  libwww was compiled with mysql but virtual/mysql is not installed

I guess this should be fixed by rev-bumping libwww.

I fail to see your problem, virtual/mysql just depends on mysql or
mysql-community, don't see how any revbump would solve anything. Run emerge
--sync; emerge -uDav world.

The problem is that I do not have virtual/mysql installed, because the old
libwww did not depend on it. I do however have the actual mysql package
installed, because the old libwww depended on that.

Now the new ebuild of tetex checks for the existence of virtual/mysql because
the new version of libwww should have it installed -- and it fails because the
virtual is not there.

This did happen after
  emerge --sync && emerge -uDN world
and could be fixed by manually doing
  emerge virtual/mysql

But if libwww was revbumped, it would not need manual action for being fixed.

You don't need virtual/mysql installed, you need mysql or mysql-community. The
virtual installs _nothing_. This plain doesn't make any sense, sorry.

Oh cool, this comes from the "hundreds of bugs reporting "cannot find
-lmysqlclient"" check in tetex.eclass. I have found exactly 3 - 14709, 67336
and 69308. 

How about that we stop checking for PEBKAC cases and remove the check?

Ping!

(QA) Although Robert was right about the revbump as virtual/mysql is a new
style virtual the check still doesn't make much sense, hence removed.
