I had the same problem getting it running on Slackware. Since it worked fine for me under Fedora core 4, I just downloaded libaio-0.3.104-2.i386.rpm and libaio-devel-0.3.104-2.i386.rpm from ftp://ftp.planetmirror.com/pub/fedor...s/Fedora/RPMS/
and ran rpm2tgz over them to convert them to Slackware packages. I don't know what package management tools you have in Mepis, but the worst case should be to manually extract them, put the libs in /usr/lib and run ldconfig.
I'm pretty sure you'll also have to do a relink all
on the Oracle stuff...
