configure tells me that I am "..using a version of $CGI that is know to have issues with Foswiki"

The full warning reads:
warning Warning: You are using a version of $CGI that is know to have issues with Foswiki. CGI should be upgraded to a version > 3.11, avoiding 3.37, 3.43, and 3.47.

This may happen even though your perl distribution is up-to-date using your operating system's package management.

One work-around is to use cpan to install the latest version of CGI directly from, but this may not be possible in all environments and should be discouraged in favour of using your system's package manager to keep modules up-to-date.

Ubuntu 10.04 (lucid) - Debian 6.0 (squeeze)

By default, this distribution's core perl-modules package ships with CGI 3.43. There is a separate packaging of a later version of the CGI module in libcgi-pm-perl, which may be installed as follows:
sudo apt-get install libcgi-pm-perl


On FreeBSD (7.x branch at least) the default perl installation includes CGI 3.43. You can upgrade to a later version that does not exhibit the aforementioned problems by installing the port (in category www):
cd /usr/ports/www/
make install

It seems the reason 3.43 is marked as problematic due to a bug which can result in double-utf8-encoded URL params. Generally, most people seem to be able to use CGI 3.43 without issue. It will cause problems if your {Site]{CharSet} is UTF-8.
