This looks like dune-grid didn't knew about ug when it was compiled, so it did
not compile the dune-bindings to ug.  You probably specified
"--with-ug=/path/to/ug" in the CONFIGURE_FLAGS in your .opts _after_ you
configured and compiled dune-grid; i.e. you only added this flag when you
started on your own module and and did not recompile dune-grid afterwards.
Make sure you have that flag in your opts file, and recompile your dune:

  ./dunecontrol --opts=your.opts configure : make clean : make

Regards,
Jö.
