OK, now here comes the one thing that really puzzled me during my debugging session \
today (although it doesn't affect the patches I just posted): gpstoge doesn't seem to \
use my updated libgps unless I build it like other programs in the gpsd package (I \
actually had to modify the Makefile of gpsd and incorporate it into the make process \
to get it to use the updated libgps).  Now, it's quite possible that incorporating it \
into the gpsd working directory and Makefile was overkill, but the way I used to \
compile it seemed to take its behaviour from the old libgps, although I had already \
make'd & sudo make install'ed the updated gpsd.

Here's how I used to compile gpstoge:

13:09 [~] robin> cc -o bin/gpstoge src/gpstoge.c -lgps

However, every time I do it that way, I seem to get a gpstoge based on the old \
libgps.

Here's what "make" does.  Obviously a lot more complicated, but can someone more \
experienced with the intricacies of linkers (i.e. almost anyone) help me with which \
is the key part that means it builds using new libgps functions rather than old ones?

Libraries have been installed in:
   /usr/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
     during execution

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Incidentally, I know the install location is different, but that's not the issue - I \
only allowed one binary copy to remain on the system at any given time, and used the \
"which" command to double-check.  Any help would be most welcome!

Cheers,
Robin
