Comment(by gale@…):

 I am stuck on this one too. Here are some details:

 I am on Mac OS X 10.6.8 on an Intel MacBook.
 I am trying to upgrade:

 glib2 2.28.8_0 < 2.30.2_1

 I get the following error:

 {{{

 }}}

 Note that the syntax

 {{{ attrs.has_key('name') }}}

 is an old synonym for

 {{{ 'name' in attrs }}}

 that was removed in Python 3.

 So this particular error is easy to fix. But I'm
 not sure how easy it would be to go through
 the python code in glib2 ourselves and ensure
 that it is all compatible with Python 3.
 That's a job for upstream.

 The real issue is that since this port does still
 require Python 2 only, we need to make sure
 that is what it uses. (And we need a dependency
 to make sure that we actually have an appropriate
 version of Python around somewhere.)

 We have run across this issue for a number of
 other ports. This one is pretty important though,
 because glib2 is a direct or indirect dependency
 for many, many ports.

 Thanks!
