 Replying to [comment:14 kencu]:
 > try this patch:

 Thank you! This solves `__Unwind_Resume` error (and likely gonna fix the
 build on 10.6). On 10.5.8 the second missing symbol prevents the
 completion:
 {{{
 Undefined symbols:
   "_malloc_default_purgeable_zone", referenced from:
       _je_zone_register in zone.pic.o
       _malloc_default_purgeable_zone$non_lazy_ptr in zone.pic.o
      (maybe you meant: _malloc_default_purgeable_zone$non_lazy_ptr)
 ld: symbol(s) not found
