Forum OpenACS Q&A: Response to openacs-apache-rpms
You can go to altavista and just copy the name of the package into the search frase. It gave me this link where there is a hole bunch of old libncurses libraries. http://www.rpmfind.net/linux/rpm2html/search.php?query=libncurses.so.4
I would recomend doing a very basic install in the begining to get things working. I couldn't get mod_perl to work alongside mod_aolserver for example, but I'm not that experinced either.
If you wan't to get serious about mod_aolserver you should also check out the work Petru Paler might be doing :https://openacs.org/forums/message-view?message_id=19176
