pkg_which will do it if you can provide the full path to the missing 
file.  Which is easy if you already have the file installed and can find 
the full path (locate libxcb.so.2), but not so easy if it's missing.

Sometimes, a simple "whereis" will help:

% whereis libxcb
libxcb: /usr/ports/x11/libxcb

If the port is missing or outdated, pkgdb -F ought to let you install 
it.

And of course there's always crushing brute force:

% find /usr/ports -name pkg-plist -exec grep libxcb.so.2 {} +
/usr/ports/x11/libxcb/pkg-plist:lib/libxcb.so.2
