The blks2 modules use the new style hierarchical blocks (gr.hier_block2). The old style (gr.hier_block) was deprecated (but still available) in GNU Radio 3.1, and now on the development trunk and in the 3.2 release, have been removed. > A question I am asking is why did the BBN people who wrote the 802.11b code > make their own DPSK mod/demod and did not use the function blocks provided > by gnuradio?

Yes, they have been tested and used in a variety of real-world, commercial applications of GNU Radio. There were a couple serious bugs in them that have been fixed as part of 3.2.
