where is ardour.rc.in?

Hi.It’s very hard to collect all dependings…

Finally,I’m trying to install ardour but scons say:

scons: *** Source ardour.rc.in' not found, needed by targetardour_system.rc’. Stop.
scons: building terminated because of errors.

How can I get it?

its part of the distribution and in the repository, at the top level.
