#3 INSTALL document should mention libgps

[Bryce Nesbitt]

Now that you depend on libgps, it would be good to mention that in the INSTALL document.
Else your readers will get:

ubuntu:gpsdproxy-0.1.0> make
cc -c -o gpsdproxy.o gpsdproxy.c
gpsdproxy.c:34:17: fatal error: gps.h: No such file or directory

So the full instructions are more like
--------------------------------------------------------
Install libgps and the development headers (sudo install libgps-dev on ubuntu or debian)
make && make install
