I'm trying to use the script at http://technotes.1000lines.net/?p=23
to serve .pl in /cgi-bin/ (like awstats) as FastCGI. Attempting to run
the script gives an error. I've tried with Perl 5.8.8 and 5.10.1. Both
result in the same error.

Can't locate unistd_64.ph in @INC (did you run h2ph?) (@INC contains:
/etc/perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux

Is this error something that is simple to fix, or is there some other
method for serving Perl with nginx?
