make install installs the CIO data file as /usr/share/supernovas/CIO_RA.TXT by default, but the default location (in novas.h) uses /usr/share/novas/CIO_RA.TXT instead when CIO_LOCATOR_FILE is not set excplicitly before the build.

Will fix for 1.4.2 to use the install location (under /usr or else as defined by datapath or prefix) as the default location for CIO_RA.TXT consistently.

In the meantime, the workaround is to set CIO_LOCATOR_FILE to /usr/share/supernovas/CIO_RA.TXT (or equivalent for datadir or prefix) explicitly prior to building and installing the library to the default location. E.g.:

  export CIO_LOCATOR_FILE="/usr/share/supernovas/CIO_RA.TXT"
  make
  sudo make install

The bug does not affect the Linux (Fedora and Debian) packages since these already defined CIO_LOCATOR_FILE like above during the package build.
