Redmine

hi i cant integrate git with redmine. I have looked at wiki topic and configure apache, grack, git but when i trying clone git repo i see

 Can't locate object method "some_auth_required" via package "Apache2::Redmine" at /usr/local/lib/perl5/site_perl/5.16/mach/Apache2/Redmine.pm line 321.\n

I change little the Redmine.pm code

package Apache2::Redmine;

=head1 Apache2::Redmine

Its more comfortable for me in freebsd.
If someone have issues for this?
P.S. with default Redmine.pm the same
Thx for help
