 sorry, I meant the link problems you were experiencing before.  That error
 message just tells us that the patch doesn't apply cleanly to trunk
 anymore because {{{configure.py.in}}} was changed in the meantime.

 Looking for a portable way to find the name of the python library I came
 across following comment in {{{sipconfig}}}:

 {{{
 # This made an appearence in Qt v4.4rc1 and breaks extension modules so
 # remove it.  It was removed at my request but some stupid distros may
 # have kept it.
 self.LFLAGS.remove('-Wl,--no-undefined')
 }}}

 Seems like {{{sipconfig}}} which is used to create the Makefiles for the
 python bindings tries to explictly filter out the link option that causes
 the link errors.  It probably just fails to because extra_lflags are not
 split in the patch and therefore there is no such element.

 r11279 now passes on the linker flags in splitted form and there are no
 linker errors.
