[Koha] Installing Koha 2 on Mandrake 9.1

[Robert Maynord]

Dear Koha Folks:

Our school library has been using Koha for a year now.  Recently, the 
Z3950 tool stopped working, and I decided it was time to begin looking 
at Koha version 2.  On a different machine, I successfully  installed 
Koha 2, but am having trouble getting it to run.  When I connect to koha 
in the web browser (Mozilla), it quickly displays the "Welcome to Koha" 
message, but then says "The requested URL /cgi-bin/opac/opac-main.pl was 
not found on this server."  I have played with httpd.conf and with the 
Koha index.html file, changing ScriptAlias and so forth. but so far no 
luck.  My httpd error log says "[Tue Aug 12 08:40:39 2003] [crit] 
(98)Address already in use: make_sock: could not bind to port 80". 

I have included a copy of the Koha part of httpd.conf below...

I thought someone might see an obvious problem that I have missed.  Any 
suggestions?
(Thanks!)
