Unfortunately that's not the case from a packaging point of view. That's
been my experience and that of all the other people I know who tried to
package argyll. Why do you think that despite being there for a decade,
and pointed to in every CMS howto in the web, Argyll had not been
included in any distribution till very recently?

jam may be modular internally but it assumes a static environment which
makes it very hard to get it to use system libraries instead of internal
copies.

We have one person trying to package bjam at Fedora, if Argyll moves to
bjam I'll poke him but that also means no one but boost uses bjam right
now.

It's a workaround. We hate workarounds Fedora-side. Things should "just
work" without bandaids. Just blacklist the thing upstream.

fdi files are hal files and the exact hal layer that manages permissions
is PolicyKit

Unfortunately documentation is somewhat the weak point of those efforts.

Anything which is able to detect system libraries and their build flags
through pkg-config will do fine. It seems to me Jam is lightweight at
the expense of every facility packagers expect in modern software.
A switch that makes argyll use dynamic linking internally would help
too. Separate dynamic libraries make license auditing easier (BTW you
haven't answered whether the GPVv2 files listed in the doc are also
GPLv3 licenced or not. If not you have a licensing conflict)
