OK, i thought everything was solved, but apparently it isn't

More to the point, the version of DBD::MySQL for my cpanel is 3.0000 - which is a bad version, especially if you are using Movable Type (which I am). The problem with 3.0000 (it was causing a lot of internal 500 errors when running mySQL databases) was solved with a patch upgrade (to DBD::MySQL version 3.0001) of cpanel shortly after the bad version went live.
I don't know what your upgrade schedule for Cpanel is or what is involved in upgrading it, but is there any way to at least upgrade to DBD::MySQL 3.0001? The 500 errors are annoying.
