It seems that there is still a problem with netpbm.  There is one test
failing:

~~~~~~~~~~~~~~~~~~~
...
== ps-alt-roundtrip.test ==
pbmtopsg3: [1]

/tmp/nix-build-netpbm-10.69.04.drv-0/source/test/ps-alt-roundtrip.test: line 46: /tmp/netpbm/bin/pbmtolps: No such file or directory
## If ps-roundtrip.test succeeds and this test fails, it is most likely
## a problem with one of the alternate Postscipt utilities:
## pbmtoepsi, pbmtopsg3, pbmtolps or psidtopgm.
## If both tests fail it indicates a problem with pstopnm or gs.
ps-alt-roundtrip.test: FAILURE

== sgi-roundtrip.test ==
sgitopnm: writing PPM image
...
