 I think this ''should'' have been fixed by {{{local/bin/sage-location}}}'s
 {{{
 #!python
 def update_library_files(R):
     LIB = '%s/local/lib/'%os.path.abspath(SAGE_ROOT)
     # The .a files should be re-ranlib'd
     os.system('cd "%s"; ranlib *.a 1>/dev/null 2>/dev/null'%LIB)

     # The .la files hardcode path info.  Fix this.
     for F in os.listdir(LIB):
        if F[-3:] == ".la":
            G = open(LIB + F).read()
            i = G.find('libdir=')
            j = i+8 + G[i+8:].find("'")
            z = G[i+8:j].strip().strip("'")
            i = z.rfind('local/')
            if i != -1:
                z = z[:i]
                H = G.replace(z, os.path.abspath(SAGE_ROOT) + '/')
                open(LIB + F,'w').write(H)
 }}}
 which is (also) called from {{{sage -upgrade}}} (i.e. {{{sage-sage}}}) if
 the installation has (newly) moved. (I'm not sure how robust that code is,
 it's at least less readable.)

 Did you perhaps interrupt this in the first run?
