     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.4.2
 Keywords:  snow leopard  |       Port:  netpbm
--------------------------+--------------------
 The problem (or at any rate, the first problem) seems to be that strnlen()
 is missing...

 'strnlen' is invalid in C99 [-Wimplicit-function-declaration]

 :info:build                 ^
