The specific error messages are:
Subroutine TWiki::O_CREAT redefined at /usr/share/perl/5.8/Exporter.pm line 65
Subroutine TWiki::O_EXCL redefined at /usr/share/perl/5.8/Exporter.pm line 65
at /usr/lib/perl/5.8/POSIX.pm line 19
Subroutine TWiki::O_RDWR redefined at /usr/share/perl/5.8/Exporter.pm line 65
Running Perl 5.8.8, no mod_perl
Those are not errors, they are warnings, and are caused by two modules both incuding Fcntl. It's a minor irritation only, and doesn't affect functionality, so dropping to Low priority.

Perhaps we could add something like
no warnings qw(redefine);
to configure and link to a bugtracker if this irritation is tracked somewhere?
