or
3. (if you have a lot of time on your hands)
download the debianised source for perl 5.8 from "unstable" and
recompile it on your woody system. do the same for any module
packages that you need. i.e. backport the new perl to the old debian.
a lot of people recommend this method. personally, i find it to be
far too time consuming, for very little benefit. far easier (and much
better tested) to just run unstable.
Back to my original question. At this point, how do you tell apt that the package is
installed.
