As far as I know, there isn't an official way to do this. What you want sounds like a useful addition to the base system to me. You could do it in a fairly gross hacky way, like the following. This is entirly untested, might not work at all and will certainly be at the cost of some alarming error messages: # mkdir -p /var/db/pkg/perl-5.8.9_3 # touch /var/db/pkg/perl-5.8.9_3/+IGNOREME # chflags -R noschg /var/db/pkg/perl-5.8.9_3 Hopefully it chucks a spanner in the works before the package system actually installs anything. Of course, you'll have to update that if the perl5.8 port has any sort of version bump[*]. On second thoughts, writing a small wrapper around pkg_add(1) that greps through the @pkgdep lines in the +CONTENTS file from the package tarball and bails if it finds the wrong version of perl would be a much cleaner approach. The -M (--master) and -S (--slave) flags to pkg_add look interesting in this context.
