Ariel,
Note that most needed steps are documented in the debian GIS policy:
http://pkg-grass.alioth.debian.org/policy/
There is a lot of information and it can be overwhelming, but know
that you probably will find many answers there :-)
The first thing you should do is to file an ITP bug "Intent to
package". (as highlighted in [1]). As an example the ITP for owslib
[2].
Next thing you probably want to do is set up an account on alioth [3].
This is where we keep our packaging work.
I'll have a look to your package later.
Regards,
Johan
