these rpms are available from rh, but aren't in the testing repo:
mysql-5.0.50sp1a-2.el5s2 perl-DBD-Pg-1.49-2.el5s2 unixODBC-2.2.12-8.el5s2
i'm not pushing to move things out of testing yet, i'm just waiting for the mysql rpm to be there. i'm assuming it isn't there because of the newer version of mysql already there, but i really want to only use the rhwas versions of things. i know that making a sub-repo or the like has been discussed, and maybe that needs to happen now to make this work?
