This turns out to be a bug in gnuradio configure - when --prefix is not specified with ./configure, the ${prefix} variable is set to NONE

http://www.mail-archive.com/autoc...@gnu.org/msg15772.html

The following code with yeild a PKG_CONFIG_PATH of NONE/lib/pkgconfig

dnl add ${prefix}/lib${gr_libdir_suffix}/pkgconfig to the head of the 
PKG_CONFIG_PATH
if test x${PKG_CONFIG_PATH} = x; then
    PKG_CONFIG_PATH=${prefix}/lib${gr_libdir_suffix}/pkgconfig
else
    
PKG_CONFIG_PATH=${prefix}/lib${gr_libdir_suffix}/pkgconfig:${PKG_CONFIG_PATH}
fi
export PKG_CONFIG_PATH

if may be more appropriate to do the following somewhere at the top of configure.ac

if test "${prefix}" = "NONE"; then
    prefix=${ac_default_prefix}
fi

gr_standalone.m4 and configure.ac both seem to have this issue

The problem being that /usr/local/lib/pkgconfig isnt honoring the
users prefix and possibly libdir. Perhaps we can still make this
right... Does this patch work for you?

Still no worky.  Must set PKG_CONFIG_PATH manually.   I confirmed that
the patch had been applied to the .m4, then did a "make distclean"
   then a "./bootstrap", then a "./configure".  The configure fails to
find UHD unless I explicitly set PKG_CONFIG_PATH.
