Replace ./mkplots with a very simple executable (or script) which does
something like writing to a file, including any error messages sent to

to the same permissions as mkplots.
This will allow you to see whether the executable is actually being
executed or not and whether any errors are being generated. In my
experience there are often problems with permissions, especially if the
script is being run by a web server.
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 ):
(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
