This is kind of dumb (and certainly not 'The Ruby Way', but I got it to 
work with this workaround.

(1) Create a little Korn shell file (save as make_plots.sh, change 
permissions with a `chmod +x make_plots.sg` ):

<i>#! /bin/ksh</i>
<i>mkplots</i>

(2)  Run it with the following command in Ruby

system( "make_plots.sh" )



However, this really offends me to have to do this, so any further ideas 
are welcome....
