Yet more info... I tried the latest UserDB.pm from git. It complained
about missing Safe.pm so I added that too. Now I get the same error:

"Sorry, there was an error in processing this form action. Please report
the error or try again later. (Can't locate object method "new" via
package "Vend::UserDB" (perhaps you forgot to load "Vend::UserDB"?) at
/usr/local/interchange/lib/Vend/UserDB.pm line 2138. )"

just a different line number. And of course that new line number is the
same "$user = $module->new(%options);"

Quite annoying indeed.
