We can't easily really know (for "make replace") what a package provides=20
before installation (especially for various platforms). I guess one idea=20
would be the pkgsrc MAINTAINER to build and install package and then add=20
the data from the PROVIDES directly into the pkgsrc package's Makefile.=20
Then it could be used at "make replace" by checking all installed packages=
to make sure the new version to be installed is adequate. (Of course there=
could be other changes that could make the replaced package incompatible,=
but it might help.)

For binary package replacing (which I do very often with pkg_add -u and my=
custom pkg_add -o for overwrite), we already have some of this information=
when you have PKG_DEVELOPER=3Dyes defined. In this case, it records the=20
SONAME provided and/or needed information. The problem is that we don't=20
have anything coded that will test these PROVIDES and REQUIRES settings.
