newbie setup question

Yes, Robert,  the problem was the upper case name.  Everything was upper
case "LE".   I have now changed it so that everything is lower case  "le"
 and it works, and appears to consistently work (quirky behavior has gone
away).  This is the first LISP program that has forced me to use lower case
;-)   Given this is my first application of asdf I would never have figured
this out.  Thank you.  I hope this will be classed as a bug.

For what it is worth, IMHO, at first blush, the *CENTRAL-REGISTRY* approach
seems better as all the project code remains in the project.  With the
other approach one strangely puts (or links) the local project build file
under a remote directory unrelated to the project.
