i am sorry, but i have trouble understanding your terminology. what is 
the difference between *building packages* and ''deployed and installed''?

i belive that when you say that ''configure must not necessarily be 
generated by GNU Autoconf'' you still expect ''configure'' to behave 
exactly as if it had been generated by gnu autotools. correct?

from what you have sofar written i think that you are creating a 
unneccessary distinction between ''packager'' and ''end users''. i 
belive that for some (pure) applications their needs are similar enough 
to treat them as one and the same.

i also think you want to force application developers to use a gnu 
development system, to make things simpler for yourself. even if other 
users of the ''application'' would have a harder time because of this 
requierment. i could be wrong again.

no need to excuse yourself, i see no irony. i have repeatedly come to 
the understanding that cpan is a reason for the success of perl.

how about if they are not packaging systems? what if they are deployment 
systems? and they knows how to tailor the ''application'' for a 
particular hardware, os and installation directory?
would it be such a nightmare for a ''professional packager'' to write 
the interface from his favored tool to these pure tools?
it would only need to be done once for each tool.

i agree about not imposing, but i do not want to have a gnu system imposed.
i think that a good erlang deployment system (for pure erlang 
applicaitons, etc) could handle uncompiled erlang.

i do not understand why it is neccessary to have several packages if the 
  deploymenmt system can handle hardware, os and installation directory.
