I'm starting to be inclined to suggest we abandon support for this kind of operation on Lispworks. Lispworks does not provide a portable means to invoke from the command-line, indeed invocation from the command line is *IMPOSSIBLE* unless you pay extra for a Professional license. Also, image-dumping is only possible if you have a Professional license.
What's even The Right Thing here? Should we be checking to see if image creation is possible? And how do we capture the fact that some of our stuff requires that the user create a LW image that can be invoked from the command line w/o starting up the IDE?
I really wish they would ship with a simple command-line executable...
Cheers, r
