In building a package, is it possible to make the package depend upon

by doing something in the DESCRIPTION file
I'd like to add a dependency to my package such that when the user install
my package it will automatically install this other package from R-forge as
well.
Not completely, the user has to choose R-forge as a repository (which is not
the default but easily selectable).
And of course on R-forge being up (and its admins tell me they never
intended it to be used to distribute packages other than to testers).
However, you can if you want to get your package to install this other
r-forge package: a package which does that is HSAUR2. That's
reasonably sure to work if the r-forge package does not contain
compiled code (just using install.packages(type="source")). Otherwise
you depend on R-forge having built the binary for the end user's
platform.
For the record, some of us are pretty unhappy about CRAN packages
having off-CRAN dependencies (and have talked about adding metadata
to say where such packages should be located) and would be very
unhappy about an R-forge one.

Any help greatly appreciated.
