     Type:  defect        |     Status:  assigned
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.8.1
 Keywords:  powerpc       |       Port:  MoarVM, rakudo, nqp
--------------------------+---------------------------------
 Assigning to myself not to forget. `MoarVM` finally received a belated
 update on what Macports uses for its master site (why not Github like
 other two?), I will update and fix wrappers. Currently they are broken –
 because, for example, `rakudo` by itself installs symlinks, and then
 `legacysupport` wrap those into a loop, binary does not get invoked. (My
 mistake, should have tried to build something ''with'' them when added
 redirect_bins.)
