I don't think that is a problem.  If you have gdm installed then you have lots 
of other libraries dragged in by gdm itself and by all the other GNOME 
components.  libselinux should be lost in the noise.

Using dlopen for SE Linux alone is not worth-while for gdm (IMHO) unless we 
find a more generic use for the mechanism (IE supporting things other than SE 
Linux).

To support that we would want to have #ifdef STATIC_BUILD or something 
similar.  That should not be hard to do.
