   VMS version numbers default to the latest.  Thus if you don't specify a
   semi-colon, you get whatever version number is highest.  "pkg.lsp" ought
   to work.  Try editing compile-pcl by hand to remove the ";7" on these
   file names.

Yes, but the question is where these versions numbers came from in the
first place.  They surely don't appear in the defsys source.

In all likelyhood, the problem is that version number of his defsys.lisp
file is 7.  Then, make-pathname-internal isn't properly stripping that
number.  You may be able to solve this problem by changing the defvar of
*pcl-directory* not to call load-truename but instead to just be the
right directory.  Or, you may have to fix make-pathname-internal.  Try
tracing make-source-pathname to see where the problem is.
