For a long time, lang/gcc was gcc 4.8, which conflicted with the
lang/gcc48 port.  (Don't ask me why the gcc port maintainer has set it
up this way, I don't know :).

Recently, on 2016-11-20 [1], lang/gcc updated to become gcc 4.9, which
now conflicts with the lang/gcc49 port.  So lang/gcc49 must be removed,
together with all its dependent ports, before lang/gcc can be installed.

I don't know why pkg can't see this as a direct replacement.  Perhaps
pkg does not have support for such metadata.
