I assume you have an installed and working copy of GNU Radio on your
system? Did you happen to change the install prefix when building?
Usually, you just have to add the path to the gruel.pc file to
PKG_CONFIG_PATH. You'll find it in $prefix/lib/pkgconfig. If
pkg-config can't find GRULE, it won't know how to find the headers or
link to the libs. You can test with:

pkg-config --modversion gruel

If that gives you a response like '3.6.3git' (or whatever version you
have installed), things are working.
