What would you prefer? I'm open to adding back unix-getenv.  Since
cmucl tracks asdf fairly closely, it seems either would be ok.

Ah, you also need the 2015-06 extra tarball since that contains the
contrib stuff.  Since this is a compatibility issue, it's probably
best if the normal tarball contained these files.  I'll make that
happen for the next snapshot.

You clearly have not been using cmucl for very long. :-)  That
search-list pathname stuff predates my involvement with cmucl.  Could
possibly predate support for logical pathnames.

It certainly would be better if the host were something like
#<lisp::search-list-host "modules"> and the :directory component could be more
like a regular list of directory components.  I did try to make that
happen briefly once but failed to succeed.  And decided that it wasn't
worth it to me.
