Forum: Ruby-Gnome 2 Fail to build Ruby/GLib on ubuntu karmic

Hi.

I upgraded from intrepid to karmic via jaunty. I updated my git
repository of ruby-gnome2 via git-svn.  Ruby/GLib failed to build. Am I
the only one ?

$cd .../glib
$ruby extconf
Failed to open '/usr/lib/pkgconfig/gst-python-0.10.pc': No such file or
directory
Package libdrm was not found in the pkg-config search path.
Perhaps you should add the directory containing `libdrm.pc'
to the PKG_CONFIG_PATH environment variable

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

I take a look at the ruby errors. I have understant that:
PKGConfig.description("gobject-2.0") failed.
I have a /usr/lib/pkgconfig/gobject-2.0.pc file but pkg-config
--list-all does not display informations about GObject.

$pkg-config --libs gobject-2.0
-lgobject-2.0 -lglib-2.0
$cat /usr/lib/pkgconfig/gobject-2.0.pc
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: GObject
Description: GLib Type, Object, Parameter and Signal Library
Requires: glib-2.0
Version: 2.22.3
Libs: -L${libdir} -lgobject-2.0
Cflags:

I have fixed this issue by reinstalling libglib2.0-dev package. It was 
installed but  I suppose that it was not correctly configured.
