Subject: Re: syntax error in 7z2john

Thank you both.  I got past the syntax error.  I ended up going to the
earlier version of Python and using the topmost/latest version of the
custom builds page.

Unfortunately now I am getting this:

 7-Zip files without header encryption are *not* supported yet!

I googled and came across this:
http://comments.gmane.org/gmane.comp.security.openwall.john.user/7012

and this:

http://thread.gmane.org/gmane.comp.security.openwall.john.user/6779/focus=6784

but wasn't able to figure out what I was doing wrong.  Any ideas that might
help me get this working?  Has this issue been addressed?
