/usr/local/pilot subhierarchy since this thing installs a *lot* of
executables and headers, many of which may well conflict with other
tools. This also makes it consistent with the prc-tools port.
Use suggestion from Satoshi to deal with PREFIX (thanks, Satoshi!).
Libraries and header files are included to allow the creation of custom
applications in C, C++, Perl5, Tcl, Java, and Python (not all are enabled
in this port).
