Use the lmc script (in the tools directory) and then 
(I have the a copy of the script in my path and just do
export WORKSPACE=`pwd` at the top-level of the source tree whenever I want
to switch workspaces around.)

Then just tell mmake to use lmc as the Mercury compiler, e.g.

 	mmake test.depend MC=lmc
 	mmake test.runtest MC=lmc
