Interesting.

Ok, that should not be a problem. It would be nice to have GAP work in
64 bit mode, but that can be sorted out later. We will dumb clisp for
ecl in the future anyway, so I would not worry too much there. The ecl
maintainer does not support AIX yet due to lack of access, but a port
should be little work since it practically runs on everything.

Nice.

Cool. Hopefully William will get access to that AIX cluster soon so
that we can start merging back fixes sooner than that.
It would be very helpful if you could post patches and notes to the
Wiki page. The output from "make check" would also be helpful. It
might happen that it hangs at some point in which case a CTRL-C or a
manual kill of the current doctest would get you past that. I would be
*very* interested in how that works out.
One bug you certainly have to fix is get_memory_usage() since that one
requires support for AIX to be added. There are likely other places
where you might run into trouble. Unfortunately getting Sage to build
up and start is only half of the battle since making it pass its test
suite can be a lot of work. For example the Solaris port has been
building more or less out of the box for well over a year, but we
still have four bugs to fix before the doctests pass.
