32-bit NCAR libraries

Hi, I met a problem on  32-bit NCAR libraries.
The corresponding codes in my script is:
 
if ( $fmt == "ras" ) then
# set CONVERT="/home/arango/bin/imconv/imconv"
#  set CONVERT="/usr/bin/convert"
  set CONVERT="/usr/local/bin/convert"
  setenv NCARG_ROOT $NCARG32_ROOT
  set CTRANS=$NCARG_ROOT/bin/ctrans
else if ( $fmt == "vec" ) then
  set CONVERT="/usr/local/bin/convert +antialias -density 108"
  set CTRANS=$NCARG_ROOT/bin/ctrans
endif

What complains when I run the script is:
NCARG32_ROOT: Undefined variable.

The NCARG32_ROOT is 32-bit NCAR libraries. What is that libraries and how to
install it?
Thank you?

By the way, I have successfully installed ncl_ncarg-5.0.0.Linux_i686_gcc4 in my Ubuntu OS. So,  what's libraries in the package(32 or 64)?
