[Distutils] checking if external dependencies are satisfied (and aborting ow).

(Apologies for cross-posting, but since this relates to both Pylons
and distutils I figured it'd be OK)

Dear All,

We are developing a web-based application using Pylons. Pylons itself
allows for easy distribution via eggs. Our application depends on
non-Python software (mainly R and a bunch of R packages). As part of
the installation, we would like to run a shell script (with possibly
some Python and R code in it), and verify if all R-dependencies are
satisfied, and if they are not, abort the installation.

Note we are not trying to get setuptools to install the R-stuff, just
run a script which checks a few things. I've searched the distutils
and Pylons lists and docs and I cannot find this addressed, but I
think I once read about this being possible. What am I missing?
