I'm looking at the use of portmaster to upgrade perl versions, and

Taking a look at devel/glib20, I see this:
USE_PERL5= yes
although from the docs in the glib tarball it's not at all clear (to me
anyway) what it's used for. Given that it doesn't seem to be a rundep
for glib20 it's also not at all clear to me why qbittorrent should have
a pkgdep for it.
Can someone please explain what the heck is going on here? (And please
note, I'm picking on glib20 because this seems to be a particularly
egregious example, but I'm really more interested in the problem generally.)
One of the scripts provided by devel/glib20 is a perl script. That is the
reason why
we need perl.
A solution in this instance would appear to be to split devel/glib20
into two ports, glib20 and a slave port glib20-scripts
The former would need no (run) dependency on perl (or python), solving
the chain problem Doug raises. The latter would have run dependencies on
both languages, but would only (as far as I can tell) ever need to be a
build dependency of dependent ports, again breaking the chain of run
dependencies on a scripting languange.
There is IMHO a separate issue (not applicable in this case) that all
too many porters have used USE_PERL5 when USE_PERL5_BUILD would be
sufficient.
