 As requested:

 $ `sudo port contents libmacho-headers`
 {{{
 Port libmacho-headers contains:
   /opt/local/include/mach-o/arch.h.mp_XXX
   /opt/local/include/mach-o/arm/reloc.h.mp_XXX
   /opt/local/include/mach-o/arm64/reloc.h.mp_XXX
   /opt/local/include/mach-o/fat.h.mp_XXX
   /opt/local/include/mach-o/getsect.h.mp_XXX
   /opt/local/include/mach-o/i386/swap.h.mp_XXX
   /opt/local/include/mach-o/ldsyms.h.mp_XXX
   /opt/local/include/mach-o/loader.h.mp_XXX
   /opt/local/include/mach-o/nlist.h.mp_XXX

   /opt/local/include/mach-o/stab.h.mp_XXX
   /opt/local/include/mach-o/swap.h.mp_XXX
   /opt/local/include/mach-o/x86_64/reloc.h.mp_XXX
 }}}
 ...where `.mp_XXX` represents `.mp_<epoch at which time the files were
 moved>`, as done by MacPorts.

 tyvm for suggesting I try to run that command, because my issue seems to
 have been resolved (will need to test on 1 more machine before I confirm
 this)

 anyway, I usually would delete any *.mp_* files under my `$prefix`, so
 this does explain why I'm encountering the error I've previously stated in
 this ticket.

 solution is of course to reinstall `libmacho-headers`, so that `sudo port
 contents libmacho-headers` would now show that same filelist, but w/o the
 trailing `.mp_XXX`, and the files would also be there as needed.
