NCAR graphic test failed

 Good night,

I installed the ncl precompiled binaries and when I tested NCAR graphics I
received the following message:

sithorjedi@sithorjedi:~/ncl_
ncar$ ncargex cpex08 -clean
NCAR Graphics Fortran Example <cpex08>

  Copying cpex08.f

  Copying cpexcc.f

Compiling and linking...
gfortran -fPIC -fno-second-underscore -fno-range-check -O -o cpex08
cpexcc.f cpex08.f -L/home/sithorjedi/ncl_ncar/lib -L/usr/X11R6/lib -lncarg
-lncarg_gks -lncarg_c -lX11 -lXext
/usr/bin/ld: cannot find -lX11
/usr/bin/ld: cannot find -lXext
collect2: ld returned 1 exit status

The compile and link failed.

The NCL test was successful, but the NCAR graphics one failed, how do I
solve this? any help would be appreciated.
