Hello list,

On my office linux box I have lyx working nicely with maxima. I installed
Maxima and Lyx on my home Freebsd box but there it does not work...
In the shell from which I start Lyx I see:

$ lyx
use equation inset
use cell: [char i mathalpha][char n mathalpha][char t mathalpha][char e
mathalpha][char g mathalpha][char r mathalpha][char a mathalpha][char t
mathalpha][char e mathalpha][delim ( ) [frac [char x mathalpha] [char 1
mathalpha][char + mathalpha][sup [char x mathalpha] [char 3
mathalpha]]][char + mathalpha][char 1 mathalpha][char , mathalpha][char x
checking expr: 'integrate(( x )/(1 +  x ^(3)) + 1,x)'
calling: echo 'SIMPSUM:true;tex(integrate(( x )/(1 +  x ^(3)) + 1,x));' |

In the document only an = appears after te equation.

When I do the echo part manually (in a terminal) I get:

$ echo 'SIMPSUM:true;tex(integrate(( x )/(1 +  x ^(3)) + 1,x));' | maxima

Does anyone have an idea on where to start looking for the solution to get
at least the example at
