How to say "package yet provided"

[Romnea Kolap Pin]

Hello:

I have the next problem, is there any way to say to Debian "this package is yet provided"?.

I mean, if I compile mplayer and I want to install the mozilla-mplayer package, which depends on mplayer, how could I say to my distro "hey! man, I have also one mplayer"?. Is there any configuration file?.

I could make a package with my own mplayer, but I think it would be really difficult  because it happens in sereval cases, for instance: in java virtual machine, in ati drivers, etc.

Romnea.
