Undefined subroutine Foswiki::Request::rearrange

I have been successfully using 1.1.9. I downloaded 2.0.2, resolved missing perl modules and now I get

Undefined subroutine Foswiki::Request::rearrange

when I try foswiki/Main (or System or whatever) or bin/configure. Nothing is written in event.log or the apache log. I am running OSX Yosemite. I don't know what to do next to complete the installation and move my topics to 2.0.2.

Can you find out what version of CGI and perl is installed? It appears that Perl is getting confused and trying to call Request::rearrange instead of CGI::Util::rearrange. The following diff makes it explicit, and should avoid the issue.

If your system has the "patch" utility installed, you can save this patch to a file named request.patch in the root of your foswiki installation. Then execute the following command:

patch -p0 < request.patch

Thanks. Some progress but not there yet. I applied the patch successfully. Now it gives me: Undefined subroutine &CGI::Cookie::unescape called My CGI is 3.63 perl is 5.18.2

-- TheodoreMankovich - 25 Oct 2015

I have no idea what's going on. CGI::Cookie::unescape() is actually CGI::Util::unescape, and it's the same patched above, but this time internal to CGI::Cookie. CGI::Cookie calls unescape and perl is picking up the wrong location. But since it's internal to CGI, I don't have a patch to suggest.

I had to install CGI::Session for 2.0.2. I used cpanm. It installed version 4.48. CGI.pm (version 3.63) on the other hand came with OSX and it is located in /System/Library/Perl/5.18. Session was installed in /Library/WebServer/Documents/Foswiki-2.0.2/lib/CPAN/lib/perl5/CGI/Session.pm. Is there some incompatability there. Maybe I should install all the needed CGI modules from cpanm. Should I try that?
