#55595: port check netpbm does not look to work
----------------------+--------------------

 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.4.2
 Keywords:  check     |       Port:  netpbm
----------------------+--------------------
 I have run `sudo port check installed` on my extended MacPorts repository
 (more than 500 packages).

 It is all fine but, alone among the 500+ packages, libnetpbm and netpbm do
 not seem to register that they have been checked.
 ```
 $ port -v
 MacPorts 2.4.2
 $ sudo port check installed
 --->  Computing dependencies for libnetpbm
 --->  Computing dependencies for netpbm
 $ sudo port check installed
 --->  Computing dependencies for libnetpbm
 --->  Computing dependencies for netpbm
 $ sudo port check installed
 --->  Computing dependencies for libnetpbm
 --->  Computing dependencies for netpbm
 ```

 Is it normal?

 Best regards,

 Luc.
