You need to set INLINEDIR or HOME in your environment.  This will be  
fixed in the next release.

You need the MS C compiler.

Your ruby wasn't compiled with GCC.  If you want inline to use GCC,  
you need to compile ruby with it.

RubyInline uses whatever C compiler Ruby was built with.  If you  
don't have the same compiler installed inline won't be able to do its  
thing.  For windows using the one-click installer you need to either  
install the same compiler or build ruby from scratch with a GCC.
