RHEL 6 / SL 6 / Centos 6

Only darktable-1.0.5 can be provided for these distributions due to
restrictions on the Glib version available. Still, try it out, 1.0 has
many nice features already and most of the hardware support has been
ported back by Pascal - that's where the .5 comes from.

   * install the linuxtech.repo config file if you don't have it already:

su - root
cd /etc/yum.repos.d/
wget http://pkgrepo.linuxtech.net/el6/release/linuxtech.repo

   * install darktable:

yum --enablerepo=linuxtech-testing install darktable

End URL install.

When I attempt to build darktable from source:

End output.

Any suggestions?  Has anyone built this application?
