New description:

 If you build Sage but do not run it, then the script {{{sage-location}}}
 does not get run, so the file {{{$SAGE_ROOT/local/lib/sage-current-
 location.txt}}} does not get written.  So if you move the Sage install
 directory before running it, the paths in the files
 {{{SAGE_ROOT/local/lib/*.la}}} are not correct.  The attached patch
 updates the paths in those files if the file {{{sage-current-
 location.txt}}} does not exist.

 (I'm marking this "minor" since it's not likely to happen at all
 frequently.  When it does happen, it can screw things up pretty badly,
 though.)

Comment:

 Except that the file's name is {{{sage-current-location.txt}}}...

 Good catch by the way, I assumed it was an even larger, perhaps OS-related
 problem.
