You will get the same result if you add it to your working directory.
And start idl with a routine from that. This makes testing easier.
After reading Ronns book I should have realized that's this will work
but I don't tried. 

What's are the licenses saying about this. Of course if you already 
have written your own DLM you are allowed to add them to each IDL
Version.
But this is a bit different from mixing two Versions of two commercial
products.

Till now gif is available for past idl5.3 users. 
Are there any ideas how much it will costs?
