The easiest way to install ikiwiki is using the Debian package.
Ikiwiki requires MarkDown be installed, and also uses the following
perl modules if available: CGI::Session CGI::FormBuilder (version
3.02.02 or newer) HTML::Template Mail::SendMail Time::Duration
Date::Parse (libtimedate-perl), HTML::Scrubber, RPC::XML,
XML::Simple
If you want to install from the tarball, you should make sure that the required perl modules are installed, then run:
perl Makefile.PL
make
make install
See download for where to get it.
