[rt-users] Can't locate Plack/Handler/Apache2.pm

[Stephen J Alexander]

The following is from a perl guy perspective (I'm no expert with RT). I
don't remember what options are available during build and install, but in
the source files it looks like /usr/bin/perl is hardcoded. So unless there
is a simpler way I don't know about, you would need to change them to point
to /usr/local/bin/perl (or whatever path you've installed the new perl on).

The files that call /usr/bin/perl within my RT installation are:
./bin/rt-mailgate
./bin/importusers.pl
./bin/rt
./bin/rt-crontool
./sbin/rt-email-group-admin
./sbin/rt-server
./sbin/rt-setup-database
./sbin/rt-setup-fulltext-index
./sbin/rt-shredder
./sbin/rt-attributes-viewer
./sbin/rt-email-dashboards
./sbin/rt-session-viewer
./sbin/standalone_httpd
./sbin/rt-preferences-viewer
./sbin/rt-server.fcgi
./sbin/rt-clean-sessions
./sbin/rt-test-dependencies
./sbin/rt-dump-metadata
./sbin/rt-validator
./sbin/rt-fulltext-indexer
./sbin/rt-email-digest

As I mentioned in a previous post, it's a bad idea to mix your perl
environments, so you may want, at a minimum, to 'yum reinstall perl' so
that your distro perl doesn't cause you headaches later.
