Redmine

..
rake aborted!
Could not find RubyGem fcgi (>= 0)
..
We receive this error and can't proceed in the install of redmine

also this failed before so we tried to get fastcgi running. Why is there actually this dependency?:
/usr/bin/ruby1.8 extconf.rb install fcgi r -- --with-fcgi-lib=/usr/local/fcgi/lib --with-fcgi-include=/usr/local/fcgi/include
checking for fcgiapp.h... no
checking for fastcgi/fcgiapp.h... no

• extconf.rb failed ***
  Could not create Makefile due to some reason, probably lack of
  necessary libraries and/or headers. Check the mkmf.log file for more
  details. You may need configuration options.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/bin/ruby1.8
--with-fcgi-dir
--without-fcgi-dir
--with-fcgi-include=${fcgi-dir}/include
--with-fcgi-lib=${fcgi-dir}/lib

==================
Any help is very appreciated.
