bug or installation error?

[Niels Grundtvig Nielsen]

Just installed the latest Ghostview on a Mandrake/Linux box (8.0). PS
files that used to display perfectly with the earlier version of GV
now generate the following messages: any tips on how to get things
working properly would be appreciated.

TIA!
