Repoman currently gives the following errors for our ebuilds:
  ebuild.allmasked: This error can be ignored, as all our packages are supposed to be masked
  ebuild.badheader              3
   games-util/fpdb/fpdb-0.20.1.ebuild: Malformed CVS Header on line: 3
   games-util/fpdb/fpdb-0.20.904.ebuild: Malformed CVS Header on line: 3
   games-util/fpdb/fpdb-9999.ebuild: Malformed CVS Header on line: 3
   not sure what the correct header is for a sunrise ebuild so leaving as-is for now
