--add libjpeg.so.62 to mmap (skip below)

### 24 Jul 2017

The mmap program requires that the shared library,
libjpeg62, is installed.  On Ubuntu 16.04, it should be
located here:

  /usr/lib/x86_64-linux-gnu/libjpeg.so.62

If it's not there on your machine, download the
libjpeg62 .deb file from here:

  https://packages.ubuntu.com/xenial/amd64/libjpeg62/download

and install it as follows:

  sudo dpkg -i libjpeg62_6b2-2_amd64.deb
