--opts is pretty much a hack, and if a package "pulls" in a dependency, 
the --opts are passed to every module that will be installed at that
point.

lin -r will 'delete' the --opts, so, you could at this point do `lin -r 
gst-plugins-base` and afterwards just `lin qt4`.

is gst-plugins-base "really" installed? what does `lvu installed 
gst-plugins-base` say?
