biblatex-biber: loadable library and perl binaries are mismatched

[bernardkelly (Bernard Kelly)]

I have a short LaTeX document that requires biber. I installed "biblatex-biber", and it seemed to go fine. But when I run

pdflatex <documentname.tex>
biber <documentname>

... I get the following error:

Magic.c: loadable library and perl binaries are mismatched (got handshake key 0xc500080, needed 0xc400080)

Macports is up to date, as are all the ports. I uninstalled & reinstalled biblatex-biber, but no difference.

I'm wondering if this could be related to the other open ticket: ​https://trac.macports.org/ticket/57398.

[drkp (Dan Ports)]

This seems like an incompatibility between one of the compiled perl modules (p5-text-bibtex, maybe) and the perl interpreter, not between biblatex and biber. Any chance you have another perl installation that could be interfering with the MacPorts one?

My Perl by default is the Macports installation, and I certainly haven't (consciously) installed any other, though I know MacOS comes with a version:

$ which perl

/opt/local/bin/perl

perl -v
