all the perl modules are installed. This is one way to install them, using
-CPAN:
+CPAN to install modules from your local machine after you extract the ikiwiki tarball:
PERL5LIB=`pwd` PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'CPAN::Shell->install("Bundle::IkiWiki")'
PERL5LIB=`pwd` PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'CPAN::Shell->install("Bundle::IkiWiki::Extras")'
