Updating devel/p5-local-lib from 1.4.9 to 1.5.1

Upstream changes:
1.005001 2010-03-10
        - I am an idiot.

1.005000 2010-03-10
        - More robust handling of running new toolchains on older perls. This
          should sort out issues users have with bootstrapping on e.g. Solaris
          and other traditional Unices. In addition, try to find a GNU tar
          capable of dealing with @LongLink so bootstrapping doesn't fail.
        - Warnings for missing PATH/PERL5LIB (as when not running interactively)
          silenced by a patch from Marco Emilio Poleggi.
        - Start of better docs for C<--self-contained> thanks to
          markstos@cpan.org.
