John, my apologies in advance for what I've written below... upon
rereading it I think it comes across a little brusque... please
forgive this and hopefully the information will prove helpful.

I don't see this part in your transcript. Would have liked to see the
specific complaint issued.

Yes, that is what should have happened. MacPorts should have picked
up where it left off.

Very odd. The wxMaxima port does declare a (runtime) dependency on
the maxima port. What does "port installed maxima" say now? If it
says it's not installed, try installing it.
$ sudo port clean --work maxima
$ sudo port install maxima
If it says it's installed, try uninstalling it, then reinstalling it.
$ sudo port -f uninstall maxima
$ sudo port clean --work maxima
$ sudo port install maxima

Yeah, now we're back into having things in /usr/local which I don't
recommend so I'm not going to deal with those errors. I'll deal with
helping you get the MacPorts maxima port installed.

It should have picked up where it left off. Maybe the port got
configured and partially made at the point where you originally
received an error, and it had found things in /usr/local, and then
you moved /usr/local out of the way and told MacPorts to continue,
and it did, without reconfiguring the port, so it got confused? That
doesn't quite make sense to me... but if that were the case, cleaning
the work area of the erroring port before proceeding should have
taken care of it, which is why I recommend cleaning before installing
above.
maxima is declared as a runtime dependency of wxMaxima. I'm not
entirely clear on how MacPorts handles a runtime dependency
differently from a library dependency. Maybe this is relevant somehow.

The gcc compiler automatically looks for libraries (and maybe
binaries, I'm not sure) in /usr/local regardless of your path. Some
suggestions have been made about how to stop gcc from doing this but
for one reason or another these have been unsatisfactory and nothing
has been implemented in MacPorts yet. Therefore, please do not have
anything in /usr/local, else it will probably get picked up by some
port you're trying to build, and you will probably run into problems.
So many problems reported on the list have been traced back to rogue
software in /usr/local that were resolved by moving /usr/local aside
that I'm no longer interested in helping anyone who insists on having
software in /usr/local while trying to use MacPorts. Putting hand-
built software in any other prefix (other than /usr/local and /opt/
local) should be ok, as should /usr/local/<anything>.
wxMaxima installed fine for me on 10.4.10, Xcode 2.4.1, MacPorts
trunk (r30016), Intel Core 2 Duo, and maxima did get installed:
$ sudo port install wxMaxima

wxMaxima.app opened for me and showed me a window. Didn't test
further because I don't know how to use the software.
