linking TeXmacs to Maxima or other lisp programs

Hi,

I've been trying to interface GNU TeXmacs with Maxima, and I have been
running into some problems.

I downloaded the a sun version of maxima, maxima-sun4-5.2-bin.tgz, and
compiled in my Sun machine. Then I went into Texmacs and started a
maxima session. But it displayed the following.

/home/bb/users/lucyz/texmacs/TeXmacs-0.3.3.15/bin/tm_maxima:
PATH=/home/bb/users/lucyz/texmacs/TeXmacs-0.3.3.15/bin:/home/bb/users/lucyz/texmacs/TeXmacs-0.3.3.15/bin:/usr/openwin/bin:/usr/dt/bin:/usr/sww/lang/java/bin:/usr/local/bin:/usr/bin:/bin:/usr/sww/X11/bin:/usr/sww/bin:/usr/bin/X11:/share/b/grading/bin:/share/b/grading/sbin:/share/b/bin:/usr/ccs/bin:/usr/ucb: is not an identifier
maxima]

When i tried to type an expression at the prompt, nothing happens, and
down in the buffer it says "maxima has died". Does anyone have any idea
what the problem is? Maybe I didn't install Maxima correctly. Right now
I can run Maxima fine in the unix shell. Or maybe I need to set some
paths. Any ideas?

My other question is how do I link TeXmacs to another lisp program. Say
I were to write a common lisp program, is there a way to start a lisp
session inside Texmacs? What is the process I have to go through?

Thanks for your help,
Lucy
