I successfully installed and used dev-perl/mime-construct-1.9 (and dependents listed below) on an AMD64 machine with full success. Please add "~amd64" to the ebuild keywords of all the packages below. mime-contruct depends on these packages which were also installed on the same amd64 machine: dev-perl/mime-construct-1.9 dev-perl/Proc-WaitStat-1.00 dev-perl/IPC-Signal-1.00
we're currently testing a new alias system, sorry for the bugspam
~amd64 keyword added. Thanks for testing. Sorry for the delay.
