gconf @2.32.4_3 does not build because of missing symbol _PyUnicodeUCS2_AsUTF8String in/opt/local/lib/gobject-introspection/giscanner/_giscanner.so

During the build process on Mac OS X 10.6.8 this happens:

Same as several other tickets. I suspect you have your python installed with the ucs4 variant.

That's right! I'll try to install the "plain" version of Python…

Gconf builds indeed with the "plain" Python package! So this one is solved.

I am just upgrading gconf to version 2.32.4_3 on Mac OS X 10.5.8 – port is reporting:

Doesn't this mean that python27 is not sufficient to build gconf here and I need to install python27 +ucs4?

[ryandesign (Ryan Carsten Schmidt)]

You have selected the python_ucs4 variant of gobject-introspection, which requires the ucs4 variant of python27. But the ucs4 variant of python27 causes the problems described in this and other tickets. So I recommend you do not use the ucs4 variant of python27 not the python_ucs4 variant of gobject-introspection.

[ballapete (Peter "Pete" Dyballa)]

This problem is related to Python 2 and its kind of handling characters beyond US-ASCII, I think. It can be closed now.
