[Derision]

If you Google that error, you will come across this thread:

http://www.perlmonks.org/?node_id=718264

Which states:

If you google for Perl_hv_common_key_len, you'll see it was added in perl-5.10.0 (perl-5.10.0-RC1), and its not available in perl-5.8.8, so you've got a version of something for perl-5.10.0 trying to be loaded by perl-5.8.8, which can't work.

So maybe try installing Perl 5.10.

(Disclaimer: I only use Windows binaries occasionally that I compile myself, so I don't know if this is the issue with the Rev703 binaries on the GoogleCode SVN).

EDIT: OK, I re-read the thread I linked to and the next post down says hv_common_key_len was addded to Perl 5.8.8/5.8.9, so I don't know. All I can suggest is when you uninstall Perl, you do:

C:\> dir perl5*.dll /s

and repeat if you have other drives than C: to ensure you have nuked all copies of Perl .dlls before re-installing.
