great to see you've got it working, well done :)
if you're worried about disk space etc., you're better off doing
'make clean' after 'make install', rather than replacing the
installed files with symlinks.
this will leave the actual files in the system directories (/usr/local/bin
etc.) and remove the build files, which are no longer needed, from
the source directories. In addition to the program executable, many
other files like *.o files are created in the source directories during
compilation -- after a successful 'make install', these intermediate
files, and the copy of the executable in the source tree, can all be
safely removed with 'make clean'.
So, generally with source tarballs, the procedure is simply:
and you don't need to mess around with symlinks etc.
