You need a version of GNURadio (that Nick Foster has out on some
development branches) that has the block.

This branch is really out of date but still has the block in question:

https://github.com/bistromath/gnuradio/tree/msk_blocks/gr-digital/lib


This branch is more recent, but the block has been removed from that
branch in favor of using an improved, more general correlate and sync
block (see my list from earlier today):

https://github.com/bistromath/gnuradio/tree/msk_from_master/gr-digital/lib


Nick probably has better advice for you.
