I can't speak to multiple platforms beyond Linux and Windows, so I'm 
curious to know any specifics from those who have experienced problems 
with portability.  Reading "perldoc perlport", there's some caveats 
about %ENV, but it has more to do with expecting certain things to be in 
it (e.g. TZ) or to mean the same thing on different platforms.  (There's 
a case sensitivity caveat that's a little concerning -- but it's a 
vague, general statement.)

At the very least, M::B uses environment variables in several other 
places to communicate with sub-processes, so I'm hoping something this 
simple is fairly robust.
