:-) Whoever said the art of dialogue was dead, was wrong! :-)

Having some kind of useful mechanism of adding extensions seems to be
a focal point?

If lisp compilers all had some way that you could add external functionality
/a la/ dlopen(3), then would this not solve the problem?

That would be the best scenario.

The above will need to find a saved_gcl, no? (I'll fix the FreeBSD port
to add this to the installed bits if so).

As an alternative install method, it suits FreeBSD very well, as all
a FreeBSD'er needs to do to build it would be

# cd /usr/ports/math/axiom
# make
# make install
# make clean

or, even easier

# portinstall math/axiom

The FreeBSD port infrastructure takes care of the details, like installing
GCL if its not already there.

Did you get his long email
