Yes, I think we all agree on that this is what we have to do, so

figuring out if the installed stuff is `good enough' for the current
package is where the problem has moved. Just testing for the
functions you want to use is cumbersome and might not be good enough,
since you might, as Derrick noted, want to know if it has fixed some
important bug. Writing autoconf tests for this is too much work (I
don't really want to spend all my time writing autoconf code), so we
would have to do version number comparisons.

Yes, it's going to be more of a burden to figure out what sets of
additional libraries you need to link with. Saying that you need to
use libtool and code in the dependencies in the .la file is not going
to sit well with everybody. The other choice is to have a
`heimdal-config' script à la gtk/gnome. Getting something that works
with same way as the stuff from the New England rebels would be great.

Currently, we do number one, and we have a macro that's called from
the top ocnfigure.in. You of course also need to package the set of
autoconf-macros with all the sub-packages.

The libraries that are used elsewhere it's the important part. I
guess telnet/whatever other applications also are separate in some
logical sense, but they're not eligible for independence yet, if
ever. If you only want/need some of them, build all and then grab the
pieces that you want, it's not like it's going to take that long on
any recent box to build them.
