Import py27-radontea-0.1.2 as wip/py-radontea.

Collection of algorithms to compute the inverse Radon transform
updated to version 1.16
fixed broken package creation
Half-baked postgis2 package.

I've had this lying around for a long time.  I'm putting it in wip so
that others can work on it as well.  The notion is that it enter
pkgsrc as postresql-postgis2 so that anyone still using postgis 1.x
can migrate, and because it's likely some future version will need to
be parallel-buildable (even if not parallel-installable).
