which ASERVE and which WEBACTIONS

I usually just use the ASERVE and WEBACTIONS that you get from the ACL
directory, i.e., the ones which are updated via (SYS:UPDATE-ALLEGRO).
But typically I also maintain a recent copy of the download tar file
in order to browse sources.  I'm running RH enterprise edition.

I just reexecuted (SYS:UPDATE-ALLEGRO) and then did (REQUIRE :ASERVE)
and (REQUIRE :WEBACTIONS).  The version that I get interactively --
ASERVE=1.2.34 and WEBACTIONS=1.5 are well behind the ones I get from
the tar file -- ASERVE=1.2.37 and WEBACTIONS=1.10.

Which should govern?  Presumably the two should be in sync unless the
tar files are "alpha".

This is not just academic.  I'm seeing some weird behavior
(unexplained slowness, possibly browser-specific) in my WEBACTIONS
application.  I want to pinpoint exactly what is happening, so I think
I want the latest and greatest unless there is some reason to be
conservative.   Can you advise?
