External program from Lisp CGI

Hi list,

I'm working on Lisp CGI based mostly on Maxima functions.
The problem is, I can't use plot2d (Maxima's interface to gnuplot) -
this function and all following it aren't executed.
But if I execute the same CGI file from terminal, it works as
expected.
I use Apache with mod_cgi on Debian.

Thanks for any help in advance.
