[ncl-install] ncargex cpex08 -clean problem

[Bill Ladwig]

The error is indicating that the linker cannot find the "libXext.so" file
(which is generally a symlink to the actual library file).  In order for
the linker to find the correct library, there needs to be a symlink with
the name "libXext.so" that should be pointing to /usr/X11R6/lib64/libXext.so.6
(and that symlink in turn (probably) points to
/usr/X11R6/lib64/libXext.so.6.4.0).  If the symlink for libXext.so does not
exist in /usr/X11R6 then you'll need to create it in there, or create it in
another path and add another -L option to point to its directory.

Hope this helps,

Bill
