Does anyone know if the gem fcgi needs fcgi to be installed on my  
machine? I’m trying to install the gem fcgi and I’m getting the  
following message:

-bash-3.00# gem install fcgi

I’d like to add that the mkmf.log has the following:  
have\_header: checking for fastcgi/fcgiapp.h… -------------------- no
