If you're using Debian or derivatives like Ubuntu, the data files in
/usr/share/proj are provided by the proj-data package.
I'm not aware of other Linux distributions that use /usr/share/proj4
instead.

PROJ4 uses the PROJ_LIB environment variable for non-default paths to
the data files. You'll need to export this variable set to the absolute
path of your custom proj4 installation before starting qmapshack
(e.g. export PROJ_LIB=${HOME}/share/proj4).
