checking for BASE_DEPENDENCIES... configure: error: Package requirements (glib-2.0 >= 2.12.0    atk >= 1.9.0    pango >= 1.12.0    cairo >= 1.2.0) were not met:

Requested 'glib-2.0 >= 2.12.0' but version of GLib is 2.10.3

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

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

===>  Script "configure" failed unexpectedly.
Please run the gnomelogalyzer, available from
"http://www.freebsd.org/gnome/gnomelogalyzer.sh", which will diagnose the
problem and suggest a solution. If - and only if - the gnomelogalyzer cannot
solve the problem, report the build failure to the FreeBSD GNOME team at
gnome@FreeBSD.org, and attach (a)
"/usr/ports/x11-toolkits/gtk20/work/gtk+-2.10.6/config.log", (b) the output
of the failed make command, and (c) the gnomelogalyzer output. Also, it might
be a good idea to provide an overview of all packages installed on your system
(i.e. an `ls /var/db/pkg`). Put your attachment up on any website,
copy-and-paste into http://freebsd-gnome.pastebin.com, or use send-pr(1) with
the attachment. Try to avoid sending any attachments to the mailing list
(gnome@FreeBSD.org), because attachments sent to FreeBSD mailing lists are
usually discarded by the mailing list software.
