 Trying to launch a GTK2 application, I was getting the following error on
 startup:
 {{{

 I tried reinstalling gobject several times as the file in question is
 provided by that port and it *still* wouldn't work. Engaging my brain and
 actually looking at the logs, I finally realized that macports was
 downloading the binary packages instead of the source…

 And it turns out that binary package apparently uses the default
 compilation options, my local Python 2.6 is installed with {{{+ucs4}}},
 and those are of course binary incompatible but Macports's binary build
 system seems unable to understand the distinction, leading to installing a
 broken binary package.
