can you check the pkg-config reported version?
like this:

pkg-config --modversion xcb

The latest released version (in 1.9 branch) is 1.9.3
if I remember correctly -5 (note "-" instead of ".") means 5th RH build of the
version before "-". In you case it'd be 5th build of libxcb 1.9. the above
command will tell.
