 No, sorry - for OS X > 10.5 there should be a programm named stackshot
 which might help
 on this - but for general purpose I've to take a close look (and ask some
 guys).

 Which would be very simple is to add debug-information (flag) to the gcc
 calls.

 It might be interesting that this problem didn't occur under 10.4 (checked
 10 Min ago,
 omicron scala, gwyddion).
 I can also check 10.5 but I suspect gwyddion is working there too. (Both
 32 Bit)

 geeky:
   * Did you install the XCode-Tools as mentioned on the
 [http://www.macports.org/install.php Install
 Page]?
   * Try xorg-xserver

 Yeti: if you look at #28666 they have also some faults with glib2 - maybe
 we can find some hints there

 kr,
