I see it's already about as tight as it could be.

After sleeping on this: I don't think we need them. 

The list of modules is compiled into libwx-perl at build time,
so the older version of libwx-perl should work with newer versions
of wxwidgets2.8, the media functionality will just not be there.

The other way around is easy: we just need the newer libwx-perl to
depend on a libalien-wxwidgets-perl package version that has
the media module information, and that should pull in the necessary
wxwidgets2.8 libraries too.

So:

1) upload libalien-wxwidgets-perl with build and runtime dependencies
   on libwxgtk-media2.8-dev
2) upload libwx-perl with a versioned build (and runtime? see below)
   dependency on that

I may get around to actually doing this if I find the time,
but obviously anybody is free to beat me to it.

Side note: I'm not sure if the modules in the Wx::build namespace are
really supposed to go in the binary package. AFAICS they are only used
for the package build. I checked a couple of reverse dependencies, and
nothing seems to be actually using those. But it's probably safer to leave
them there, and keep the runtime dependency on libalien-wxwidgets-perl
(but make it versioned too.)
