Hmm, okay, I think I get more of the game being played here.  I've
implemented it differently in the Fedora spec:

In %install:

# Need for Xinerama support
ln -s -f ../../../../%{_lib}/libX11.so.6
%{buildroot}%{_libdir}/nx/X11/Xinerama/libNX_X11.so.6
ln -s -f ../../../../%{_lib}/libXext.so.6
%{buildroot}%{_libdir}/nx/X11/Xinerama/libNX_Xext.so.6

Though these probably should just get done in the Makefile.  But the
relative paths might be tricky.

and:

 Summary:        Xinerama extension to the NX Protocol
 Requires:       %{name}%{?_isa} = %{version}-%{release}
+Requires:       libX11%{?_isa}
+Requires:       libXext%{?_isa}

(%{?_isa} gets the architecture correct)

 %files -n libNX_Xinerama
 %{_libdir}/nx/X11/libNX_Xinerama.so.1*
+%{_libdir}/nx/X11/Xinerama/

No need for %pre/%post
