That is i386 only, which will be problem a problem if I run ppc but I don't
know why I get an import error on i386 10.5 maybe it's two different
problems. I'm thinking I might need to pass the  -isysroot and
-mmacosx-version-min
flags to fink when it builds librsync, but currently fink doesn't work
saying I need to install Developer tools, despite having Xcode 3 and 4
installed.
