This breaks installing MySQL:

nelchael ~ # emerge -avt dev-db/mysql

These are the packages that would be merged, in reverse order:

As a workaround, you can mask dev-db/mysql-community:

  echo dev-db/mysql-community >> /etc/portage/package.mask

It's a bug in portage that's triggered by some code which is
supposed to help avoid circular dependencies. Here's the relevant
piece of the emerge --debug output:

Parent:    ('ebuild', '/', 'dev-db/mysql-5.0.76', 'merge')
Depstring: perl? ( >=dev-perl/DBD-mysql-2.9004 ) =virtual/mysql-5.0
Priority: medium-soft
Virtual Parent:    virtual/mysql-5.0
Virtual Depstring: || ( =dev-db/mysql-5.0*
=dev-db/mysql-community-5.0* )
Candidates: ['=dev-db/mysql-community-5.0*',
'>=dev-perl/DBD-mysql-2.9004', '=virtual/mysql-5.0']

What you can see there is that it's selecting mysql-community to
satisfy the PDEPEND. I'll make a patch for portage so that it won't
trigger the circular dependency avoidance code when it's trying to
satisfy PDEPEND.

Great! Thank you. Masking mysql-community helped.
