This is because with your spec file gem is directly installed under
%buildroot. So some C codes in the gem (usually under ext/ directory)
are compiled under %buildroot and the string "%buildroot"
is embedded in the built binary (with "gcc -g"). This will make 
/usr/lib/rpm/check-buildroot complain.

The correct way is to expand (install) gem file once under %_builddir
(at %prep or %build) and and copy all (under %_builddir) under
%buildroot at %install like:

-------------------------------------------------------------------
%prep
%setup -q -c -T
mkdir -p ./%{gemdir}
export CONFIGURE_ARGS="--with-cflags='%{optflags}'"
gem install --local --install-dir .%{gemdir} \
            --force -V --rdoc %{SOURCE0}

%build

%install
rm -rf %{buildroot}
mkdir -p %{buildroot}%{gemdir}
cp -a .%{gemdir}/* %{buildroot}%{gemdir}
....
....
-------------------------------------------------------------------

With this debuginfo rpm will also be created correctly.
