Ugh :(

Well, that version had a tendency to generate an empty lib/zmacs/commands.lua 
if zlc
couldn't find all its dependencies.  I notice that I didn't remember to commit 
all my
recent changes back to the repo - though, I still really need to bail out 
sooner before
zlc outputs an empty file (added to my TODO list).  Let me know if the empty 
file is
your problem, and I'll figure out a way to diagnose it better.

I also added another patch to give a better error when bin/zmacs can't find an 
interpreter,
but since you're running lib/zmacs/zmacs (to set the paths automatically) that 
doesn't
help.

Please pull the latest version, and show me the differences between our output 
if you're
still stuck.  Here's my terminal log:
