Exactly.

I use the following in gaim for a similar purpose.  It is rather ugly 
but works.

# Require Binary Compatible glib
# returns bogus value if glib2-devel is not installed in order for 
parsing to succeed
# bogus value wont make it into a real package
%define glib_ver %([ -a %{_libdir}/pkgconfig/glib-2.0.pc ] && pkg-config 
--modversion glib-2.0 | cut -d. -f 1,2 || echo -n "999")
Requires:       glib2 >= %{glib_ver}
BuildRequires:  glib2-devel

This way the SRPM can build on any version of glib2, but the package 
enforces the install-time version of glib2.
