Remove the option to install DRMAA .jar files as they are not
automatically downloadable due to the move the the sun donwload
center. Adding a new port to install them or adding an option to use
the manually downloaded would probably be a good idea, but I've been
stalling the upgrade too long as it is.
There are significant conceptual differences between SGE 5 and SGE
6 so potential upgraders should beware. At the file level the two
are entierly incompatable so SGE 5 must be removed before SGE 6 is
installed.
The port has seen limited testing so beware.
