Various of the PDL demo programs only work
if their prerequisites are present. The demo
list would be better generated dynamically so
that users would not see demos they couldn't
run. This might also allow for a command line
demo program as well...

Specific examples: with no PGPLOT installed, the following demos don't work:
pgplot, OOplot, transform, cartography, and bad2. If the demos could use an
alternate plotting package, that would help.
