Update

Using Ubuntu 20.04 (focal).

The module has been tried using pybind11-dev  ver. 2.5.0 and  ver 2.9.2 from tarball without success

(gr_modtool bind works OK, cmake, make, make install works OK.  Trying to run causes the python

exception gr::block not found).

The Ubuntu 20.04 package manager provides pybind11-dev v 2.4.3 only.

Then uninstalled v 2.9.2 (which is a proper superset of 2.5.0) since 2.9.2 tarball creates an uninstall rule

( 2.5.0 does not create an uninstall rule).

Next pulled pybind11-dev  2.6.2 in from Ubuntu Impish by manipulating APT and installed

only that from the package manager, then cleaned up APT to prevent anything else from updating.

The 2.6.2 installed via APT gives exactly the same problem, gr::block exception.

Does anyone have advice on how to fix?
