[ncl-install] /usr/bin/ld: cannot find -lX11

[Mary Haley]

You need to install the X11 development libraries and headers.  This
should also fix the other problem that you posted to ncl-install
about.

I'm not a system administrator for linux systems, so I'm not entirely
familiar with the process of installing X11 on them.

For Ubuntu, it looks like you may need to install the libx11-6 and
possibly libx11-dev packages.

I googled this topic, "how to install x11 on ubuntu", and saw an older
post that mentioned:

   sudo apt-get install xlibs-dev

Somebody on this list will hopefully correct me if this no longer
applies!
