"pango @1.26.0_0+macosx" breaks "meld @1.2_1"

[cduvivier@…]

A recent upgrade (58293) bumped "pango @1.24.5_0+macosx" to "pango @1.26.0_0+macosx".

This new version makes "meld" broken/unusable. Starting meld makes the python interpreter endlessly run some pango code.

Going back to "pango @1.24.5_0+macosx" (using method described at ​http://journal.bitshaker.com/articles/2007/10/20/install-old-versions-of-ports-using-macports/) fixes the problem.

Uninstalling "pango @1.26.0_0+macosx" and using "pango-devel @1.25.6_0+macosx" instead is also problematic.

Since I don't use meld, it will be more efficient for you to ​report this directly to the developers of pango.

meld is now at 1.3.1 (​http://git.gnome.org/cgit/meld/), maybe the solution is to update the meld port (later meld may be more compatible with latest pango).

Updating meld was already requested here.

I've also filed a bug against pango regarding this issue: ​https://bugzilla.gnome.org/show_bug.cgi?id=596674

If anyone else has the issue, the way to restore a working meld is:
1) Add a line with "​file:///Users/Shared/dports" before the rsync line in "/opt/local/etc/macports/sources.conf", this will tell port to also use some local packages.
2) Run "mkdir -p /Users/Shared/dports", this will create a directory for local packages.
3) Run "cd /Users/Shared/dports && svn co --revision 58292 ​http://svn.macports.org/repository/macports/trunk/dports/x11/pango/ x11/pango/", this will load the old working version of pango as local package.
4) Run "portindex /Users/Shared/dports", this will create a file port need to see the local packages.
5) Run "sudo port uninstall --follow-dependents pango" (keep a list of what gets uninstalled), this will properly uninstall the newer problematic pango and evrything depending on it.
6) Run "sudo port install meld", this will install meld and its dependencies (including the old working version of pango)
7) Install whatever else you missed which was uninstalled by 5)
