The VMS equivalent tools have a command procedure to "choose which
version of <product-name> you want" and that command procedure defines
logical names where shareable images (similar to DLLs I think) can
be found.  The name inside the image points to the shareable image
via the logical name.

How about having the default method point to the "standard place"?
Those unwary beginners do not care about multiple versions.
