build.log

On Gentoo we run compilations inside a sandbox system to prevent unwanted
access to files and devices from "real" system. That way, we are getting now
errors on some packages when gst-plugin-scanner is run as it wants to access to
/dev/video0 directly. 

Looks like this is caused by the v4l2 plugin as we only get the error when it's
present. I am unsure if it's normal that the plugin tries to write to that
device when gst-plugins-scanner checks for its existence :/

The attached full build.log is from farstream-0.2.6, whose building calls
gst-plugin-scanner and hits this problem

Thanks a lot
