Ooh - a utility called "sw_vers"!  I wonder what other hidden gems are 
lurking, essentially undocumented, on one of Apple's finest products?

After over 40 years of Unix programming, this Mac never ceases to astonish 
me...  No, I'm not being sarcastic (for once).

Anyway...

And, err, how do I achieve that?  I have this odd expectation that 
MacPorts "just works" i.e. the dependencies have been taken care of for 
me.

Speaking of Xcode, I keep being offered to upgrade it, but it will only 
run on High Sierra.  The first time I tried that, I got a message about 
something being incompatible with this box which I couldn't write down 
fast enough before it reverted to Sierra.  The next time I tried (paying 
more attention this time), it bombed out because a critical file was 
missing...  I suppose I'd better start putting money aside from my old age 
pension (yes, I'm a pensioner) to buy an Air or something.
