Hi DongInn,

I have reinstalled from a fresh distro just to be sure that the problem
was not due to an error during installation.

I think that the error is already visible at step 2 ("About to run
/var/lib/oscar/packages/switcher/pre_configure for switcher >>> No
pkg_config found"). I will try to investigate why and maybe send a message
to the oscar-devel list.


Thank you so much for the support.
Mathieu
