I don't see axp, archzoom and archway as a perl module, these are regular
unix-like applications that happen to have $(sharedir)/perllib/.

I think only arch-perl should/could be installed using CPAN.  And this
should be fully optional, only if someone wants to save several kilobytes
of hard disk, or to develop his own arch-related stuff.  I do think that
it is a good thing for every front-end to carry the specific version of
arch-perl it relies upon.  What is exactly the problem with the current
"make install prefix=/usr" that you try to solve?  Don't forget that as
any normal application, a front-end may also install images and more.

I don't see a reason to install ArchWay::, ArchZoom:: and AXP:: classes
from CPAN. Take a look for example at autoconf and automake modules.
It would be a mistake to require installing Autom4te:: and Automake::
from CPAN, they are useless outside of their applications. If you think
something from the other namespaces are generaly useful, it should be
simply promoted to Arch:: namespace.

So I suggest you to start with adding CPAN installation to arch-perl
[I still think Module::Build is a non-option; none of my 4 machines I
work with including sc.net have it.]  Then front-end makefiles may be
modified to optionally not install Arch:: classes if the proper perl
wide installation is found.

Regards,
Mikhael.
