Just try and locate the repo with those missing packages, unless centos6 hasn't built them or something wierd like that.

Same thing happening here, on SL6 and CentOS6. So its not just you.
Unfortunately I've had to switch to OpenLDAP for a bit until I can get
this resolved (probably not for another month...). The weird thing is a
lot of 389-ds packages are built and sitting in the EPEL repo, but
389-ds-base isn't present and all that perl madness is just missing. I
did find the lack of discussion a little odd -- seems like people would
notice this missing.

If anyone knows a magical workaround that would permit a proper 389
install it would be greatly appreciated (like "Geeze, get with it you
knuckleheads, its been relabeled to the 390-ds now, duh.").
