This is exactly correct.  Copy the source code directories for the 
module that need to be changed to any place on the system (your home dir).
First thing to do is change the Gmakefiles to reflect the name of a 
different executable.  For initial development this name is often of 
an executable that will be installed in the source directory. Update,
modify, etc.  When ready to unleash on the local user community, modify
the Gmakefile to install the executable in the appropriate GRASS location.

If the code is great, send it back to the entire user community!
