BTW, I'm going to be out of town for a week, so any further responses
will be delayed.

That's my point.  People are just not going to find that acceptable,
at least they didn't with year 2000 hardware with XEmacs.  Even if
it's done while you're getting morning coffee---because it will take
longer than that.  Waiting for it to load every time you reload AUCTeX
will wear out the AUCTeX developers.

No.  These are package dependencies, not version dependencies.  If a
package uses macros from another one, it is placed in the "REQUIRES"
make variable.  Then the libraries from those REQUIRE'd packages are
preloaded using the -l argument to emacs.

Theoretically these could be autogenerated, but the dependency
trackers we've seen so far have all been buggy, and miss more
dependencies than when doing it by hand.

Sure.  I don't think XEmacs will change its commitment to a more
sophisticated ("intrusive and inflexible" if you prefer :-) packaging
system.  I think we should be able to achieve interoperability in most
cases though.
