I don't follow you here. By "normal" do you mean foregoing the advanced
features of the viewer that depend on the patched fltk and dynamically
linking against the distribution supplied libfltk.so? Short of replacing
the system libfltk.so, I don't see a reasonable way to build a dynamically
linked viewer with all the bells and whistles.

I think that most people that have chosen to incorporate the patched fltk
would link it statically, and in order to make anything portable
(particularly for platforms that don't natively have fltk) you pretty much
have to. I don't have any dogmatic objections to building against the
patched fltk, I think the features are well worth the overhead. It's
unfortunate that Fltk has not accepted so many of these patches after all
this time and I'm not sure what needs to happen before they will.
So here's my suggestion:
Add a 'contrib' directory to the trunk and in it keep a copy of not only
the most current build recipes, but also distribution-specific packaging
scripts, patches, etc. I know that there is already a buildscripts
directory, we could alternatively update that but I would like to see it
under the trunk for packaging convenience. This at least archives the
patches that are necessary to build on certain platforms and provides some
additional templates for people that wish to build from source. I'm OK
with taking responsibility for this if no one objects.
Also, we should probably migrate this discussion to the devel list.
