  27 # which get into $GUILE_LOAD_PATH, leading to '..' in the module file names
  28 # recorded by Guile.  To avoid that, make sure we get a real absolute
  29 # directory name.  Additionally, use '-P' to get the canonical directory name
  30 # so that Guile's 'relative' %file-port-name-canonicalization can actually
  31 # work (see <http://bugs.gnu.org/17935>.)
