Hi, I left this issue to rest, and picked it up today, finally got it working! First, I re-installed the package, thinking that something might have gone wrong there. But the real - simple - fix was to change the 'use lib' line to

use lib "/served/httpd/docs.../perllib/lib";
[download]

so the path seen from the server (/served...) and the 'lib' subdir. I remember I tried both a week ago but in my general confusion not both together... thanks again for all your replies. I joined this list because of that problem, but browsing around I definetely will stay because there are interesting problems in discussion...
