Where does "sane-config" come from? If it's from the sane-backends
source package, all of the -dev packages should have been installed,
because otherwise the sane-backends build wouldn't work. If it's from
the sane-backends-dev RPM, I think that RPM should depend on all the
necessary -dev RPMs to build a frontend. That's the whole idea of
sane-config.

I think this is ok.

That's a bug IMHO (but I don't really know RPM based systems).

The READMEs of the frontend should mention that you need the -dev
packages. Just to be sure...

I think so. At least I don't know of anything the frontend developers
could to to avoid this situation.

Debian Sarge:
$ apt-cache show libsane-dev
Package: libsane-dev
[...]
Depends: libsane (= 1.0.11-3), libusb-dev (>= 1:0.1.6a-1), libieee1284-3-dev (>= 0.2.3-1), libjpeg62-dev

Looks ok for me but I didn't test.

Bye,
