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