Looking at your installation error messages, I do have to wonder what version of Perl that you have installed, if you are using an older version you may not have Scalar::Util installed.

Scalar::Util is also a module that really needs a c compiler to implement all the functions because they of the xs code. If you have an Activestate version of Perl installed on your system, be sure to upgrade to the most current version because Activestate will compile modules for you that use the XS code.
