Hello Daniel,

sorry for the late followup, i wanted to make shure the symptoms weren't
caused by local problems (my two boxes had different version of libtool).
I was able to 'fix' the problem by doing the following:

 - added '-module' option to 'LINK = $(LIBTOOL) --mode=link $(CCLD) -module ....'
   in the Makefile for gnome-xml and libxst. This allone didn't help but from the
   little i understand about libtool it might be a good idea anyway.

 - I add -lxml2mod to the 'LINK' line in xslt. Hmm, i'm not happy with that since 
   i also needed to add '-L/usr/local/lib/python2.1/site-packages' to the command.
   After that i got the following:

|    rmattes aiolos:/usr/local/src/libxslt/python$ ldd .libs/ 
| => not found
| => /usr/local/lib/ (0x40014000)
| => /usr/local/lib/ (0x4003c000)
| => /usr/local/lib/ (0x40048000)
| => /usr/lib/ (0x400e3000)
| => /lib/ (0x400f2000)
| => /lib/ (0x40114000)
| 	/lib/ => /lib/ (0x80000000)
  The unresolved libxml2mod is caused by /usr/local/lib/python2.1/site-packages not 
  being in the LD_LIBRARY_PATH but doesn't matter since Python adds it at runtime.

  So, i got it working, but it doesn't seem clean. Any ideas on how to fix it?
