I've been looking for it for a while as well, the only place I've seen that has it in any form is actually on the 11/780 running at the LCM (which you can of course access with a free account, if you just want to use VCL). I assume it must still exist elsewhere but it was removed found archived anywhere, sometime around 90-91 I believe? There were several other CL and LISP implementations for VAX VMS but they've all fallen into the great memory hole as well. KCL in particular seems like it might be easier to find since it was freely available, but I've had no luck.
