RFC: FreeBSD DB Port Reform

[Oliver Eikemeier]

Hi Matthias,

>        USE_BDB_VER or WANT_BDB_VER or something that presets a set of
>        variables, for instance BDB_VERSION, BDB_INCLUDES, BDB_LIBNAME,

No WITH_* options in bsd.ports.mk, they are supposed to use as make arguments
to communicate user => port.

That violates hier(7). How about moving them to libexec?

Same as above. How about lib/db-N.M?

The symlink should not be necessary.

Could you explain stupid people like me again what you gain by not simply
renaming the libraries to libdb-3.3, libdb-4.0 and libdb-4.1 and leaving
the other stuff as it is now?

IMHO ports that expect a BerkeleyDB.N.M directory under /usr/local violate
hier(7), and does this approach work with the ldconfig -r LIB_DEPENDS checking
we have in bsd.port.mk?
