------------------------+--------------------------------
 Reporter:  bgschaid@…  |      Owner:  macports-tickets@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.1.2
 Keywords:              |       Port:  cloog
------------------------+--------------------------------
 After upgrading of cloog from  @0.16.3_2 g++-mp-4.6 doesn't work any more:

 {{{
 dyld: Library not loaded: /opt/local/lib/libcloog-isl.2.dylib
   Referenced from: /opt/local/libexec/gcc/x86_64-apple-
 darwin11/4.6.3/cc1plus
   Reason: image not found
 g++-mp-4.6: internal compiler error: Trace/BPT trap: 5 (program cc1plus)
 }}}

 Symbolic link to /opt/local/lib/libcloog-isl.3.dylib "fixes" this issue
 (but then a similar thing happens with th upgraded ISL)
