It would appear the -g option was removed from the delegates file sometime between 6.3.6-10 and 6.3.7-10 for ps:* and pcl:*. This is causing problems when trying to read in a pcl format. I noticed the ps delegate entries had the same change. Running with the delegates file as installed produces the following:
bb010:image/test>./display_pl sample_files/sampoutput/bench_pcl.pcl
Unable to open 101.6x101.6 for reading.
display: PCL delegate failed `sample_files/sampoutput/bench_pcl.pcl'.
Adding back the "-g%s" "" as it was in 6.3.6 allows display to read the format properly. Is there a reason for this? Was this for ps:* only decodes?
