Thanks, but I do not have read permission for the gnuplot-4.0.0-1.src.rpm
file :-(

And one more question: would it be possible to get a src.rpm for the
LONCAPA-prerequisites rpm for Fedora? I'd like to rbuild it for SuSE.

And indeed proved to be easy.

That worked beautifully - I just rebuilt the SuSE perl-HTML-Parser-3.35
rpm with that patch.

I fully intend to do that - it'll make my live easier for future upgrades :-)
Right now I simply changed distprobe to set $dist to fedora2 when it
finds 9.1 in /etc/SuSE-release. That's a band-aid solution at best.
Thus, it would be helpful to now which files would have to be changed
so that distprobe could return something like suse9.1 (for simplicity
right now I still want to treat it like fedora2 and look for differences
later [like httpd.conf in /etc/httpd instead of /etc/httpd/conf]).
I search for files that contain the the string 'fedora', but only found
files that deal with CHECKRPMS (which I ignore for now, but basically
I just have to replace "yum" with "you"). I also grep'd for "DIST", but
could not quite figure out whether that is used anywhere other than
loncom/build/Makefile. Can you enlighten me?
