I haven't (and it shouldn't fail). Comments:

1) Don't use 'sudo' for cmake and make test, unless really necessary.
2) You can build gr-howto-... for educational purposes, but I strongly
recommend using gr-modtool instead.
3) In general, if a test fails, use 'ctest -V -R <+REGEX+>' to obtain
the output of the failed test.
Provide that in any email here.
