www-apps/bugzilla-2.22.1 currently RDEPENDs on <=dev-perl/DBD-mysql-2.9007 because DBD::mysql 3.0003 to 3.0006 are broken. 2.9007 is currently marked stable. According to the software matrix in the Bugzilla FAQ (cf. URL specified above) DBD::mysql versions >= 3.0007 are working fine with Bugzilla (which I can confirm for 3.0008). Some packages depend on newer DBD::mysql versions, though (e. g. dev-perl/Template-Toolkit-2.15-r1), which causes conflicts, of course. Therefore, I suggest to either change www-apps/bugzilla-2.22.1's RDEPEND to something like mysql? ( >=virtual/mysql-4.0 >=dev-perl/DBD-mysql-3.0007 ) which shouldn't be a problem as 2.22.1 is marked unstable itself or stabilize >=dev-perl/DBD-mysql-3.0007.
fixed, thanks
