Errors in port Makefiles: emacs20 and postgis

[Bill Fenner]

===> chinese/emacs20
"/a/fenner/ports/chinese/emacs20/../../editors/emacs20/Makefile", line 67:
warning: duplicate script for target "post-install" ignored
"/a/fenner/ports/chinese/emacs20/../../editors/emacs20/Makefile", line 68:
warning: duplicate script for target "post-install" ignored

I guess editors/emacs20 gained a post-install target, while chinese/emacs20
already had one?

===> databases/postgis
cd: can't cd to /home/fenner/portsurvey/ports/databases/postgresql-server
"Makefile", line 52: warning: "cd
/home/fenner/portsurvey/ports/databases/postgresql-server && make -V WRKSRC"
returned non-zero status

bsd.database.mk isn't included until postmk, so ${PGSQL_VER} isn't
defined when PGSQL_SRC!= gets run.
