libxcb-xlib.so.0 does not exist anymore.  Current XCB does not build or
ship it, and xcb_xlib_lock no longer exists.  If an application (or more
likely some library that application links to) still uses that symbol or
library, the application or library needs rebuilding against current
Xlib and XCB.

Note that due to the insanity of some build tools, sometimes
applications end up linking against libraries that they don't actually
need but their dependencies do, such as libxcb-xlib.
"objdump -p /path/to/application | grep NEEDED" will show you the exact
list of libraries the application links against.  If libxcb-xlib appears
in that list, the application needs rebuilding; otherwise one of its
dependencies does.

Kinda pointless for a mail sent to a public mailing list. ;)
