Indeed that lead fixed all the problems (which are apparently caused by
xcb-util).  From the bug

    Gilles Dartiguelongue 2011-05-09 08:23:52 UTC

    Please rebuild xcb-utils after running through as much packages as
    possible with revdep-rebuild. From irc discussions, it looks like
    xcb links to itself and/or pollutes some la files which ends up in
    these weird problems.

So merging a few manually from the revdep-rebuild list, the merging
xcb-util and repeating, eventually clears up everything.
