Follow-up Comment #2:

I'm running Mint 18.1 (build atop Ubuntu 16.04) and I also have a default copy
of gl2ps (1.3.8) installed by the packaging system.  I built a copy of 1.4.0
which I chose to install in /usr/local.  Since /usr/local is on the default
LD_LIBRARY_PATH I pick up the new version without having to resort to
exceptional measures.

If you really want to put the new gl2ps in an out-of-the-way location then I
think you are stuck having to tell the program at runtime where you have put
the library using LD_LIBRARY_PATH.  You can semi-automate it by setting up the
LD_LIBRARY_PATH variable in your .profile or .cshrc file.

Alternatively, you could create a file in /etc/ld.so.conf.d which contains the
extra path that ldconf should search.  This, however, will make most
applications switch over to the new library.
