To know which command cause the problem, try to do the following:

1. Do "make test 'ARGS=-debug'"
2. By the '-debug' option, image files /tmp/l2hXXXX/pXXXX.pnm will 
  remain (XXXX is certain number). Please check that the file 
  /tmp/l2hXXXX/pXXXX.pnm given to pnmcrop exists and the size is 
  not zero.
3. Try to do the each command above by hand without pipelines:

  /sw/bin/pnmcrop -verbose < /tmp/l2hXXXX/pXXXX.pnm > 1.pnm
    (configure says "pnmcrop -verbose" has no problem)
  /sw/bin/pnmcrop -bot -sides < 1.pnm > 2.pnm
  /sw/bin/pnmcrop -l -sides < 2.pnm > 3.pnm
  /sw/bin/pnmcrop -r -sides < 3.pnm > 4.pnm
  /sw/bin/pnmcrop -l -sides < 4.pnm > 5.pnm
  /sw/bin/ppmquant -floyd 256 < 5.pnm > 6.pnm
  /sw/bin/pnmtopng -interlace -trans 'gray85' < 6.pnm > 7.png

I think you will find which command make the failure.
