this is, where the package system should come into play.
turn a knob, and you allways get the -dev and -doc packages (if they exist).
writing this mechanism is a no-brainer, it just needs to be on our

yes, a guideline on naming packages is certainly needed.
includes and static libraries go to -dev,
documentation goes to -doc,
latest cvs goes to -cvs,
latest development release goes to -unstable.

it is all about consistency.

this is exactly what debian (and some rpm-distributions) do.
they just split the (one) package into three.

this has some advantages:
packages are way smaller.
(e.g.: libfreetype6 340,9kB, libfreetype6-dev 676,1kB)
dependency management is easier.
(if you install -dev, you know, you need libc6-dev and zlib1g-dev, how could
the package manager know if this is installed without -dev packages.
only with additional hooks.)

as this is more or less debians approach, we seem to agree on this ;)
