Thanks for all the response.

I take it then that the newer buildlink framework cannot deal with this
on its own and one has to use the shell-like expression matching and
the older make variables to specify alternates?

How would I specify alternates that live in different directories of
pkgsrc e.g. devel/alt1 and sysutils/alt2? Would it be:

BUILD_DEPENDS+={alt1>=1.1:../../devel/alt,alt2>=2.3:../../sysutils/alt2}
