 The current version of `libsdl2` fails for ppc, therefore I tried to
 install an early version which does not seem to have any arch restriction.
 However it fails, complaining of SDK:

 Since ppc is supported in 10.6 SDK, it still might build, but how to point
 the port to the SDK? Apparently it does not look into /Developer. (I have
 pulled a 10.6 SDK from an installation of 10A190 just to try quickly and
 the error output did not change. I will try in 10.6.8 Rosetta later.)
