Comment (by evanmiller):

 One of my fantasy projects is to get this Boost assembler code to work
 properly on PPC. It's possible that the correct logic is to disable
 context/coroutine on PowerPC rather than on 10.4/10.5. Maybe for now you
 want something like:

 {{{
 if {${os.platform} eq "darwin" && (${os.major} < 10 || ${build.arch} eq
 "ppc")} {
 }}}
