error caused by Octave-forge function __grcmd__.oct

[Aakash Dalwani]

Hi,
   Octave-forge function __grcmd__.oct is throwing the following error 
when Octave starts-up

"error: API version 2.1.50 found in .oct file function `__grcmd__'
      does not match the running Octave (API version api-v18)
      this can lead to incorrect results or other failures
      you can fix this problem by recompiling this .oct file
error: failed to install dld function `__grcmd__'
error: evaluating argument list element number 2
error: near line 1 of file 
`/home/octave-forge-2006.03.17/build/graceplot//PKG_ADD'
error: source: error sourcing file 
`/home/octave-forge-2006.03.17/build/graceplot//PKG_ADD'"


I am using Octave version 2.9.5 and I configured octave-forge in the 
following manner:

export PATH=/home/octave-2.9.5/build:$PATH
export OCTAVE=/home/octave-2.9.5/build/bin/octave
export LD_LIBRARY_PATH=/home/octave-2.9.5/build/lib:$LD_LIBRARY_PATH
export MKOCTFILE=/home/octave-2.9.5/build/bin/mkoctfile


./configure --with-path=/home/octave-forge-2006.03.17/build 
--prefix=/home/octave-forge-2006.03.17/build


If I am running an interactive job then I can proceed after the error, 
but if I have to submit a job, the PBS job exits after the error message.

How do I get rid of it?

Thanks,
Aakash
