MacPorts deliberately does not support this; there are no metrics to
find out when to consider such a port outdated and the build does not
yield reproducible results. If you need this, create a local portfile
repository, copy the grass Portfile to this tree, modify it to fetch
from current git head and change the commitish whenever you need a new
version. You'll probably have to add a artificial version number (like a
date) to get port to recognize that grass has been updated, since git
commits aren't monotonic.

BTW: MacPorts will not stop you from specifying HEAD or master as git
commit to fetch. You can use sudo port upgrade --force grass to build a
new version then.
