[GRASS-user] Two questions re 6.4 and OSX 10.4

[Richard Chirgwin]

  Hi,

I'm running a MacBook Pro with 10.4.1 (burned too many times with 
upgrade instability; now that it's running nice, I don't feel any desire 
to upgrade the OS!).

My main question is this: how can I install the new 6.4 without 
over-writing my existing install? (Just in case I have trouble with the 
new version). Noting, of course, that because I'm on an aged OS, I have 
to use the compile-from-source instructions for OSX.
