Yes, but I'll say again that the "install if prereqs exist" part is IMHO
the wrong approach: this must not be a compile-time or install-time
check, it must be a runtime check. This may be as simple as trying to
load the DSO and assuming the required keychain and/or wallet features
aren't available if the load fails.

Imagine for exaple that you start off with a GUI-less installation, with
Subversion installed, then decode to install a GUI and all the
associated shebang. Now imagine describing a GUI dependency like, "if
svn is installed then install that other extra svn package". Horrible.

(Well ... you often get e.g. an 'emacs-nox' package that's different
from (and conflicts with) the regular 'emacs' package. But there's no
security issue involved there, unlike in the case we're discussing.)
