install ncl_ncarg-5.2.1.Linux_i686_nodap_gcc432.tar.gz

Dear Sir/Madam,

I am trying to install ncl_ncarg-5.2.1.Linux_i686_nodap_gcc432.tar.gz on
RHEL6 with ifort and icc. The point is that i could run first two
example(ng4ex gsun01n , ncl gsun01n.ncl ) in your website (
http://www.ncl.ucar.edu/Download/install.shtml). but i can not run the last
example which is ncargex cpex08 -clean. it gives me this error :

    NCAR Graphics Fortran Example <cpex08>

  Copying cpex08.f

  Copying cpexcc.f

Compiling and linking...
gfortran -fPIC -fno-second-underscore -fno-range-check -O0 -o cpex08
cpexcc.f cpex08.f -L/home/ehsan/Documents/NCL/5.2.1/lib -lncarg
-lncarg_gks -lncarg_c -lX11 -lXext
/usr/bin/ld: cannot find -lXext
collect2: ld returned 1 exit status

The compile and link failed.

What should i do ? i really appreciate your help.

Best Regards

Ehsan Beigi
