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.
Comment on Re: getting error while using par-packer 0.976
Perl_hv_common_key_len was added to 5.8.8/5.8.9
I came accross the same error, its a problem with all the PAR from
trouchelle58, and theoryx5 and bribes.
ActiveState doesn't have PAR::Packer.
My solution was to switch to strawberryperl.
