Hi all,
I tried to use \psplotDiffEqn. In a simple example:
\def\Func{ neg }
\psplotDiffEqn{0}{1}{0 0.1}{\Func}

latex gives no error however gv gives the following message
Error: /undefined in F2
Operand stack:
   0.0   --nostringval--   F1
Execution stack:
   %interp_exit   .runexec2   --nostringval--   --nostringval--
--nostringval--   2   %stopped_push   --nostringval--   --nostringval--
--nostringval--   false   1   %stopped_push   1   3   %oparray_pop   1   3
%oparray_pop   1   3   %oparray_pop   1   3   %oparray_pop   .runexec2
--nostringval--   --nostringval--   --nostringval--   2   %stopped_push
--nostringval--   --nostringval--
Dictionary stack:

--dict:175/300(L)--   --dict:38/200(L)--   --dict:104/200(L)--
Current allocation mode is local
Last OS error: 2
GPL Ghostscript 8.54: Unrecoverable error, exit code 1

I have installed new pstricks-add, pst-func,  xvalkey and put *.pro files in
an appropriate place.

I will be thankful for a help.
