#38865: gcc48: remove unused dependency
-------------------------+--------------------------------
 Reporter:  manphiz@…    |      Owner:  macports-tickets@…
     Type:  enhancement  |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.1.3
 Keywords:               |       Port:  gcc48
-------------------------+--------------------------------
 Starting from GCC 4.8, graphite has been migrated to cloog+isl, so the ppl
 dependency is actually unused. The attached patch removes ppl from
 dependency and corresponding configure option. The same should be applied
 to gcc49 as well.
