Okay, I've left it simple for now, and just ran configure without any options.

When I run john, I only get this now:
$ ./john --incremental zipfile.john
Using default input encoding: UTF-8
No password hashes loaded (see FAQ)
I realize this is a FAQ, but none of the answers in this FAQ question
have helped me figure this out. The previous version I was using was
working okay.
I've deleted the old attempts from the previous version and recreated
the hash file. This is the contents of the zipfile.john:
zipfile.zip:$zip$*0*3*de3c868ba87dcff820dd1f8123b6b02f*f96a:::::zipfile.zip
I really have no idea where to go from here :-(
Thanks,
Alex
