Yes, I think we should fix this as well, I don't like things like SDL 
to be linked when not really needed, for example.
So far the policy has been to just check every possibly used lib
from configure, no matter wheter it is asked by user to be enabled.
I think we might keep this policy and move the disabling of some 
packages from within the local Makefile.am files, using the conditional
variables set at configure time to specify a configuration.
What I'd really like is to find out how to specify dependencies in the
proper subsystem rather then duplicating the info in all of them.
For example, *every* GUI-related dependency should be in the gui/Makefile.am
and *only* there, where automake and friends should derive the deps whenever
another subsystem whiches to link against libgnashgui.la. So far I couldn't
find a quick solution for this.

Fixed, thanks.
