Currently no.



I would like to figure this out:
 >>> On the DartConfiguration.tcl:

This is just a configured file at the end of the day.
And the .in file has this:

MakeCommand: @MAKECOMMAND@

So, if the cache has:
MAKECOMMAND:STRING=/usr/bin/make -i -j8

Then it should work...

Might be a double configure thing going on or something....
