 Most of them will probably already be available in your installation. You can check version numbers with the =configure= script, or if you're still trying to get to that point, check from the command line like this:
 <verbatim class="bash">
 perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'
 </verbatim>
 For more detailed dependency information, try the script =dependencies_installer.pl= located in the =tools= directory, which makes perl module installation easier. Run it with option =-h= to understand basics. This script requires confirmation before it actually does something.
 
+Foswiki ships with a copy of =CGI::Session= in order to run the =configure= script.
+
+The following dependencies are usually met by the Perl core installation: =Carp=, =CGI= (see note above), =Config=, =Cwd=, =Exporter=, =File::Basename=, =File::Glob=, =FileHandle=, =File::Path=, =File::Spec=, =File::Temp=, =IO::File=, =MIME::Base64=, =POSIX=, =Socket= and =UNIVERSAL=.
