Okay to stabilize? In tree since (31 Aug 2011).
do it, please.
The only thing in the tree that depends/rdepends on dev-perl/Date-Pcalc is www-apps/otrs, which doesn't have ia64 keywords. It's not even clean from the ChangeLog why ia64 was stabilized. As such, I'm going to drop the keywords here to ~ia64 and close this bug.
