I don't know if it should be -- and pkgsrc doesn't force anything like
that now. (If we did then @pkgdep would become like @blddep but instead of
being a specific version it would be a >= range.)

If it works, it works.

For probably over a year, I have been using a binary packages on systems
that do not have any pkgsrc building. I pull over the new binary packages
and install them. I don't install the dependencies to latest versions
unless it is specifically forced. (I use my custom pkg_add -r or -u to
replace packages in place as needed.) Very frequently I have binary
packages using dependencies older than what they were built with (simply
because the @pkgdep allow it).

This has seemed to work fine. And it makes it fast for reinstalling
packages.

Usually the only problem (now rare) I have is when someone (including me
:) forgets to bump a BUILDLINK_RECOMMENDED when the shared library names
change.

I was thinking about that and it seems to be a fine way.

I guess it won't hurt for me to update gcc on my non-pkgsrc box and the
open-ended gcc3-c++>=3.3.4 will allow it to work. I was just wondering if
that was required since I saw the PROVIDES= and REQUIRES= indicate that it
is not required.
