It looks like you're mixing an XS module built for 5.10.x with Perl 5.12.0.
This doesn't work because the 5.10 and 5.12 series are binary incompatible.

The perlapi-* dependencies are designed to prevent this sort of breakage:
all the XS module packages in sid are currently uninstallable with 5.12.0,
and they have to be rebuilt against 5.12.0 to fix this.

If you use a non-packaged perl, you don't get this protection. I suggest not
including /usr/lib/perl5 and /usr/share/perl5 @INC and installing any modules
you need manually.
