I have seen several report gr-pager compilation problems.
I ran into this on a computer. The solution was straightforward. I did
not
have <> of the packages from
http://gnuradio.org/redmine/wiki/gnuradio/UbuntuInstall
installed because given the apt-get command indicated on that page
resulted
in some installed packages. Once done, I did a
make distclean
./bootstrap
./configure
make
and all went well.
