That's very helpful -- thanks or explaining it.  (Perhaps Jason meant
the same thing, but I did not understand his reply).

I am keen to use a recent svn because of some specific changes and
bugfixes.  Do you know when there will next be a proper PARI tarball
released, or can I make my own (as Jason suggested)?  (Is what "make
release means?)
