[Bioclusters] Sequest Cluster problems

I've wasted rather too much time on bioworks over the past few weeks.  I
managed to get it working, (master on win2003 and slaves on debian), but
it wasn't a pleasant experience.

A few "top tips":

Before you start pvm on the master, make sure there a no stray pvm
processes hanging around on the slave nodes. (the master tends not to
clean up after itself particularly well.)

Check that the slave nodes are configured *exactly* as detailed in the
instructions. There are a lot of hard coded paths in the bioworks code, so
if pvmd or the ini files are somewhere other than where the docs say they
should be (even if they are on your path) it won't work.

AFAIK the master can only run on windows, so you're stuck with that.

If you want details on our config, let me know.
