[rt-users] Undefined subroutine &RT::Authen::ExternalAuth::UserExists

Hello,
I'm sorry I don't know more about this, but I never will at this rate.
I don't know where to begin. I still get
Undefined subroutine &RT::Authen::ExternalAuth::UserExists
Despite multiple reinstalls and following various flavors of install
instructions and HOWTOs.
I see the sub UserExists is defined in
/opt/rt3/local/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth
.pm
Which is readable by the webserver user and group. So:
- is this a perl problem, it not seeing that sub?
- is it the webserver, not finding the file?
- is it something else entirely?
Hours of searching generic 'undef sub' perl issues are too varied to be
useful (tho I've checked over a few things), and the only results for
this particular issue are my own messages on this list. If you think I
should be bugging someone else about this, that's fine with me: any idea
who..?
Thanks,
