I found the problem. Epiphany links with:
<snip>
-Wl,--rpath -Wl,/opt/gnome2/lib64 -Wl,--rpath -Wl,/usr/lib -Wl,--rpath
-Wl,/opt/gnome2/lib64 -Wl,--rpath -Wl,/usr/lib -Wl,--rpath
-Wl,/opt/gnome2/lib64/xulrunner-1.8.1.2pre

Notice, "-Wl,--rpath -Wl,/opt/gnome2/lib64/xulrunner-1.8.1.2pre" is at
the end. It should be before "-Wl,--rpath -Wl,/usr/lib".

Adding the following to my .jhbuildrc allowed me to work around the
problem:
os.environ['LDFLAGS'] = '-Wl,--rpath
-Wl,/opt/gnome2/lib64/xulrunner-1.8.1.2pre'

I added bug 397557 with this info.
