The zeromq internal openpgm implementation was bumped to 5.2.122 on Dec 2012, but the ebuilds in tree still have =net-libs/openpgm-5.1.118 as the dependency. net-libs/openpgm-5.2.122 is in tree since Dec 2013 and stable across the board since Mar 2014. Could the dependency be adjusted accordingly in at least zeromq-3 and zeromq-4 ?
Fixed! Thanks for report
