Your machine has an obsolete version of the C library which 
is incapable of properly handling the code for detection
of what characters are spaces.

There is some code in GTK+ to try to detect this situation
and fall back to simpler methods, but it may not properly
detecting all such configurations.

As a workaround, you should be able to configure GTK+
with the folllowing command line:

 CPPFLAGS=-DG_HAVE_BROKEN_WCTYPE ./configure
