I was having problems even getting it to pickup my faked Fedora or Red
Hat install, so I just "edited" it out.  I'll see what I can come up
with.

Here's the error which led me to the changes for lonnet.pm:

[Fri Oct 15 15:05:37 2004] [error] Usage:
random_set_seed(@seed)\n at seed[0,1] must be two integers in the range
(1,1) to (2147483562,2147483398)\nand usually comes from a call to
 random_get_seed() or\nrandom_seed_from_phrase($phrase). at
/home/httpd/lib/perl/Apache/lonnet.pm line 4899\n


Here's the diffs for lonnet.pm, very simple fix, I added the logthis
line to make sure things were behaving :

test-srv1:/src/loncapa-1.2.1/loncom/lonnet/perl # diff
/src/loncapa-1.2.1/loncom/lonnet/perl/lonnet.pm
/home/httpd/lib/perl/Apache/lonnet.pm
