multimedia/vlc does not configure (x11-xcb)

[Rhialto <rhialto%falu.nl@localhost>]

with pkgsrc 2011Q1, in pkg_comp with 5.0 userland running on 5.1.

This seems somewhat similar to my woes with kdelibs3, in the sense that
some pkgsrc infrastructure seems to go wrong. This time, it is x11-xcb.

Also, it seems like it could use some options for optional dependencies.
I see several in the configure output even though I don't know what they
are:

dirac
schroedinger
fluidsynth
ZVBI
LIBASS

and further up (logg not reproduced here)

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XLIB_XCB_CFLAGS
and XLIB_XCB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
