Question

Any idea why CPAN is locked in circular dependencies although I only issue get?

This only happens when I started from a fresh Perl install (or delete CPAN/source directory):

Perl is ActiveState Perl v5.16.0 on Windows 7 64bits

CPAN.pm is 1.9800

My guess is that this is a bug in the Makefile.PL. I suggest you try installing B::Hooks::OP::Check first.

You also might try using cpanm which doesn't try to be so clever and so is less fussy
