Technically, I meant it's possible to walk back until you find a 
'self' that's a different Distribution instance, at which point you 
can ask for an easy_install command and check for a prefix.  You're 
probably better off doing that than trying to parse argv, especially 
since the prefix might be coming from a configuration file anyway.
