You don't need to add the libs/spirit directory to your sinclude path.
That's just where the examples, tests and documentation resides. Sorry, I
should have been more explicit.

I certainly can only guess what happens there, but I think the checkout
svn checkout https://svn.boost.org/svn/boost/trunk/boost/spirit
creates a directory ./spirit. Could you try moving this into a subdirectory
boost, additionally. The final directory structure must be:
And the -I $SPIRIT21_ROOT needs to be added to the compiler command line.
All spirit headers are included as
that means you need to tell the compiler the base directory the
'boost/spirit/...' is in.

Seems to be the correct revision.
