Perl's idea of a metapackage to provide c library dependencies for perl sdl application.

when building from source, this package can be used to detect and get configuration settings from an installed sdl and related libraries. as a binary package, it provides information on native libs used when building this package.

regarding the native c libraries, all packages built with libalien-sdl-perl must have at least the same build dependencies than libalien-sdl-perl. since this list if not fun to maintain, this metapackage depends on all packages used to build libalien-sdl-perl (and also depends on libalien-sdl-perl).
