Hi,

I’m trying to install fcgi-0.8.6 on Mac OS X but I keep getting this  
error:

I have XCode 2.1 installed already. Where do I find the location of  
ruby.h if XCode tools is already installed?

I do not know how OSX works, so try the \*x way;  
open a console and type in:

find / -iname ‘ruby.h’

It tries to locate the file in any directory  
under the root. If the file is found, you will  
see its location. You can then provide this  
location to extconf.

If the file is not found, you must look for  
some sort of alternative ‘development’ package  
(or you could use Fink or DarwinPorts) to get  
the headers.
