Did you use the snapshots on the wiki or compiled the latest version from 
source? It seems the snapshots are quite old and there have been recent 
commits since. (I don't know if those fixed or broke things though.)

Linux can read hfs+ file systems and the EFI partition can also be mounted 
and written to on OS X from the command line so it's easy to copy boot.efi 
over to the EFI partition either on Linux or OS X.

Right. Hopefully it does not rely on Apple's specific HFS+ support in 
their firmware or that's compatible with what (at least one of) the EFI 
drivers provide.
