Okay, a stupid question:
I want to fiddle a bit with the "webcollage" screen saver, so I look at the source code, a Perl script.
Fine and good, and easy enough to read and change. So I tried to run it from the command line, and it said it couldn't find the "djpeg" program.
The screensaver runs just fine when run from xscreensaver, so my path must be wrong/insufficient, I thought.
So, let me just find it, so I'll set up my path:
sudo find / -name 'djpeg' -print
Only: Nada. Nothing is found.
Oh well, perhaps it's part of some Perl library, so it's called "djpeg.pl" (as opposed, strangely, to "jpegtopnm" and similar functions which do exist) or something, so let's be more exhaustive:
sudo find / -name '*djpeg*' -print
Only, I still find nothing. What am I doing wrong here? And how can the webcollage script find djpeg when running from xscreensaver when it can't when I run from the command line?
Any help would be appreciated.
regards
Carsten
