!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
======================== FATAL ERROR ===========================
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
We have a number of reasons to believe that this is a development
checkout and that you, the user, did not run `perl Makefile.PL`
before using this code. You absolutely _must_ perform this step,
to ensure you have all required dependencies present. Not doing
so often results in a lot of wasted time for other contributors
trying to assit you with spurious "its broken!" problems.
By default DBICs Makefile.PL turns all optional dependenciess into
*HARD REQUIREMENTS*, in order to make sure that the entire test
suite is executed, and no tests are skipped due to missing modules.
If you for some reason need to disable this behavior - supply the
--skip_author_deps option when running perl Makefile.PL
If you are seeing this message unexpectedly (i.e. you are in fact
attempting a regular installation be it through CPAN or manually),
please report the situation to either the mailing list or to the
irc channel as described in
