Ok, I have modified initGRASS() and named it myinitGRASS().  I have just 
changed a couple of lines to prepend the grass64svn directories, rather 
than append them, to PATH and LD_LIBRARY_PATH.  These appears to work 
fine, but I don't know what other ramifications it might have:

The new lines I have are:
