Simon, can you paste or attach the output of perl -V

Can you launch the script in the debugger?

perl -d /usr/lib/cgi-bin/openguides/wiki.cgi

(does it crap out before getting to the debugger prompt?)

No. Stepping throught he code, the last step before the error was: DB<1> n main::(/usr/lib/cgi-bin/openguides/wiki.cgi:215): 215: $guide->display_node( 216: id => $node, 217: version => $version, 218: oldid => $oldid, 219: redirect => $redirect, 220: ); DB<1> n

If the answer to this is yes, it craps out, you might still be able to find out how far it's getting with Devel::Modlist (you will probably need to install this module from CPAN).

I'd also suggest getting help from somewhere else, like perlmonks or the London.pm list.

Yes that might be necessary, since it's system-wide. Argh! You might have noticed, my Perl-fu isn't particularly strong.

Hmmm. Digging through strace I found the last thing referred to was /usr/lib/perl5/auto/Cwd/Cwd.so which is part of libfile-spec-perl. Removing that resolved the problem.

So why would this module be getting touched if it's not actually in use?

That's in a distribution called Pathtools, but was originally part of the perl 5 core. Cwd and File::Spec are pretty much core modules.

Now to attempt to write a bug report that will actually be useful.

The best thing might be to construct a failing test.
