[gentoo-user] What is this new python error? "'--active' option cannot be used"

[Arttu V.]

Hello,

Can anybody hint what on Earth this following message means, I've
never seen anything like it:

 * Messages for package dev-python/sip-4.9.3-r1:

 * ERROR: dev-python/sip-4.9.3-r1 failed:
 *   PYTHON(): '--active' option cannot be used in ebuilds of packages
supporting installation for multiple versions of Python
 *
 * Call stack:
 *     ebuild.sh, line   48:  Called src_install
 *   environment, line 3362:  Called python_need_rebuild
 *   environment, line 3231:  Called PYTHON '-A' '--ABI'
 *   environment, line  205:  Called die
 * The specific snippet of code:
 *                   die "${FUNCNAME}(): '--active' option cannot be
used in ebuilds of packages supporting installation for multiple
versions of Python";


I can see the most recent change in the eclass touching this part over
at s.g.o, as well as read the code, but it didn't make me any wiser so
far:

http://sources.gentoo.org/viewcvs.py/gentoo-x86/eclass/python.eclass?rev=1.82&view=log

But then again, it says it fixes something for the 2.1-series portage
users. Is this now broken for us overly brave portage 2.2_rc users?
