New description:

 Currently, libGAP doesn't give useful errors if something goes wrong
 during initialization.

 Also, the GAP SIGINT handler got installed, this is fixed in the new spkg.
 Now Ctrl-C works as expected.

   * Start with sage-5.6.beta3 or later.
   * Install [http://www.stp.dias.ie/~vbraun/Sage/spkg/libgap-4.5.7.spkg]
   * Apply [attachment:13588_libGAP_root.patch] to the root repository
   * Apply [attachment:trac_6391_libGAP.patch] to the Sage library
   * Apply [attachment:trac_13588_improve_libGAP.patch] to the Sage library
   * Apply [attachment:trac_13588_exec_fix.patch] to the Sage library
   * Apply [attachment:trac_13588_manifest.patch] to the Sage library

 The `trac_6391_*` patch has already been reviewed at #6391.
