Internet DJ Console configure failure

[Sean Bruno]

I'm attempting to install http://www.onlymeok.nildram.co.uk/index.html
and seem to have all of the required dependencies installed, yet I'm
getting a configure error that doesn't make sense to me.  What package
is configure attempting to check for here?

>= 2.6.0) were not met:

Package gobject-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gobject-2.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'gobject-2.0', required by 'PyGObject', not found

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

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