Works for me. Use "Download ZIP" to the upper right here, extract and
run make in the directory:

*-devel ports are pre-releases, beta or unstable. You usually do not
want them unless you really need the bleeding edge.

Use an absolute path:
$ port provides /opt/local/include/glib-2.0/glib.h
/opt/local/include/glib-2.0/glib.h is provided by: glib2
If instead you meant you do not know which ports provides a specific
file, there is unfortunately no index available for that.
