Would you perhaps have multiple installs of gnuradio both in /usr and
/usr/local? That could be one issue

Also, while its ok to put gnuradio in /usr and grextras and pre-cog into
/usr/local. You will need to set the GRC_BLOCKS_PATH environment
variable to have entries for both block paths. The paths would be
your_install_prefix/share/gnuradio/grc/blocks
