gr-baz installs duplicate blocks: Warning: Block with key "zeromq_sub_source" already exists. (etc.)

[rxseger]

When .gnuradio/config.conf is configured with the local path gr-baz installs to:

[grc]
local_blocks_path=/usr/local/share/gnuradio/grc/blocks

then gnuradio-companion complains about blocks that already exist in the "stock" GNU Radio distribution:
