Hi Michael - it worked. Thanks!
I upgraded Raspbian Jessie to Debian Jessie and was able to install
gnuradio 3.7.10.1 from source.
The CFLAGS at that URL are for pi2 - for the pi3 I used
CFLAGS="-march=armv8-a -mtune=cortex-a53 -mfloat-abi=hard
-mfpu=neon-vfpv4 -O2"
but
CFLAGS="-march=armv8-a -mtune=cortex-a53"
will work too - as well as not setting CFLAGS.
