"EPL" generally stands for the "Eclipse Public License", for example in the FSF's list at <http://www.gnu.org/licenses/license-list.html#EPL>.
This already led to confusion, resulting in addition of EPL to the wrong license group, see the attachment in bug 152593 comment #43.
I suggest renaming the Erlang license file to "Erlang" or "Erlang-1.1". AFAICS it is used only by dev-lang/erlang. It should then be added to the @MISC-FREE license group.
I would suggest adopting SPDX¹ naming policy.
OSI also uses the SPDX short-form identifiers, which we could make use of as well.
Sadly the website is down for maintanance at the moment.

It's still in Google's cache. They label it "ErlPL-1.1" which of course would be fine for us.
Erlang Public License v1.1
Other web pages for this license
Unless you raise objections, I'll rename the license file to ErlPl-1.1 (following <http://www.spdx.org/licenses/>) and update the ebuilds in one week from now.
Sorry I didn't get around to it, please go ahead.
