or try this:

fgrep -rZl /usr/lib/libxcb-xlib.la /usr/lib* /usr/kde/*/lib* | xargs
-0 sed -i -e 's:/usr/lib/libxcb-xlib.la::g'

this strips out the /usr/lib/libxcb-xlib.la from the various packages
in /usr/lib and /usr/kde/<all versions>/lib (if you've prefixed kde to
/usr/kde) directories that have incorrectly been injected with
libxcb-xlib.la dep. after that you should still rebuild those
packages, if you've used static linking, and this time they should be
able to build just fine. you can use this command to strip out .la
dependencies (remember that statically linked libs still need rebuild
after the change of a library that they depend on).

here's flameyees post, about preserved libs with references to the use
of .la files, from which i've picked up this technique i've used more
than once with gcc (which always triggers a rebuild when built with
gcj support):
