Hi ppc64/sparc. Could you please test either sys-cluster/torque or sys-cluster/openpbs and mark them with ~arch, or put 'pbs' in your package.mask? lam-mpi only builds it's PBS batching support if a PBS implementation is detected (there is no way to control it unfortunetly). Once you have done so, please re-add your ~arch flags to sys-cluster/lam-mpi-7.1.1-r2
added ~ppc64 to torque and deps. readded ~ppc64 to sys-cluster/lam-mpi-7.1.1-r2, too.
torque (and also openpbs) do not install the .tcl files correctly without correcting bug 101326, so pbs is currently masked on sparc. There is a long explanation at https://bugs.gentoo.org/show_bug.cgi?id=101326#c20.
sparc should be good to test now.
This was fixed a long time ago, closing, and i've unmasked the pbs USE-flag.
