udpcast now installs the file /usr/include/rateGovernor.h. What's the purpose of this file? Can it be used by external programs, so that it has to be installed?

Yes, as described in http://lll.lgl.lu/pipermail/udpcast/2008-September/000887.html, this is for use by an external program, a "rate governor" that decides how fast to send data. This is useful for instance when sending data over satellite, so that the satelitte interface device ("multiprotocol encapsulator") can instruct udp-sender to slow down the transmission if less satellite bandwidth is available.
