I tracked this down to r1751167, which is only on trunk and 1.10.x.
Long story short: it is wrong to require swig in order to configure the
swig bindings. The whole point of putting generated swig wrappers into
the release tarballs is so that users can build them without having to
install swig.
Defining the symbols SWIG_PY_COMPILE, SWIG_RB_COMPILE, and so on, should
depend on the various scripting languages being installed, not on the
presence of Swig.
Can anyone explain the reasoning behind this change?
