HI all -
I tried making expr take just the filename without the path in the test,
and got an unintended consequence I can't understand (if you make both an
expr and an expr~, for instance, the .so gets loaded twice).
So I backed off from that but t least fied the error message. so for now
at least, in vanilla at least, it isn't possible to invoke expr (etc.)
via path.
I don't know if there are ther external objects like expr in that there
are symlinks (or copies) of the binary by different names that the object
uses to disambiguate itself. I rather doubt it, but OTOH there's a lot of
stuff out there.
cheers
Miller
