Comment (by jhpalmieri):

 If you build sage 5.3, then move the installation, then upgrade, then
 dependency_libs is not fixed. The reason is that files in lib64 aren't
 touched by the old version of sage-location, just spkg/install, and
 spkg/install only fixes libdir. Then later, when sage-location is run, it
 looks for the path in libdir, then changes other paths in that file to
 match them. But once the path for dependency_libs is not in SAGE_ROOT and
 is not related to the path for libdir, sage-location can't fix that path.

 In practice, I applied the patches here, #13407, and #13452, to
 sage-5.4.rc4, built a copy of sage 5.3, moved it, and upgraded it from the
 patched 5.4.rc4. The path for dependency_libs was not fixed.
