There isn't any good reason that I can see. Moreover, it causes all
kinds of problems. For example, many packages on ftp.netbsd.org which
depend on perl are broken with the latest perl, since it can't satisfy
the dependency on modules which are now included with the base perl.
Also a problem for gv and freetype-lib (and thus, gnome).
To get rid of that mess, there are now two places which require
changes. The easy one, would be to remove the section in the
"fake-pkg" target which collects dependencies in installed binary
The messier one to fix now involves numerous changes to buildlink.mk's
...but I'm not sure if that applies to buildlink2.
Rather than repeat myself, this one sums up my thoughts on the subject
