I think this is happening because you didn't specify a path for --with-
opt-include. Arguably this is a bug in mkmf. Line 1345 is this:

idirs =3D idir ? Array =3D=3D=3D idir ? idir.dup :
idir.split(File:ATH_SEPARATOR) : []

idir is set by the with_config method, which can return a value, true
or false. The dir_config method will choke on true or false, though.

Anyway, try dropping the "--with-opt-include" option or specify the
path and see if that helps.
