It doesn't seem to like your mysql, as it lists it as incompatible. As
a side note, I have to ask why you built mysql in /opt. If it's to get
mysql5 support, rpms for that exist for centos, and don't require
rebuilds of anything else. It's situations like the one you're in that
make package management a worth time investment, doesn't matter if
it's .deb, rpm or even emerge or whatever gentoo calls it.
