I worked around that one by changing the AC_MSG_ERROR to AC_MSG_RESULT
so it would echo vs exit. Same for gettext. And ran autoconf to make a
new configure script. glib2 did not seem to respect it but I enabled
enabled --with-libiconv=no. This was still not enough as gconvert.c was
still unconditionally including iconv.h. touching a blank iconv.h in
glib-2.6.7/glib/iconv.h did the trick and allowed it to compile for the
first time. I ended up wrapping an #ifdef around the include file vs
using touch.

http://oc12.net/~solar/glib-2.4.6-no_iconv.patch (updated psm version)
http://oc12.net/~solar/glib-2.4.6.ebuild

I'm still not sure about that free() in the iconv_close() function.
Don't know if/where memory is being allocated in the first place for the
iconv_t struct. Either we will be trying to free invalid pointers or we
wont.
