Hm. Gentoo is not LFS.
Gentoo does not require the user to have build-time-knowledge or to underst=
and=20
autotool-magic.

I am doing this package-maintainer-related stuff because I want a newer=20
courier package and there is no maintainer. I noone brings courier up to=20
date, it will be kicked of the Gentoo distribution very soon, I think.

We all don't want that. :)

Hm, it's a dependancy problem of the "we must re-run autotools because of t=
he=20
version mismatch".
See below.

No it won't, Gentoo is not that dumb. But it's okay, If sysconftool is=20
something local, then the package should patch it away if Gentoo does a=20
better job instead.

Hint: No, I don't say Gentoo's etc-update is absolutely better than this,=20
especially as I did not really understand how to use sysconftool. But Gento=
o=20
has such a tool in place and it works for all and every config file in my=20
system and it's just a matter of consistancy to use that instead. No flames=
=20
please.

It's Gentoo. ;-)

Okay, so I'll keep that in place.

Hm, there is a very (very, very) small number of packages where a re-run of=
=20
autotools is required. So I think there must be any solution.
I'll stay with that, or better, I switched from running all autotools to=20
running just libtoolize and aclocal. That's a matter of a second,=20
autoconf/automake needs minutes.

Because there are some Variable changes about libtool. That's what I found =
out=20
in the net.
I'll write some statement about Gentoo later, perhaps that could make some=
=20
things more clear.

autoconf and automake, not configure. Configure is (IMHO) part of the build=
=20
and is absolutely okay. But autotools should not be run.
