27 | # By default we may end up with absolute directory names that contain '..', |
28 | # which get into $GUILE_LOAD_PATH, leading to '..' in the module file names | |
29 | # recorded by Guile. To avoid that, make sure we get a real absolute | |
6171070b LC |
30 | # directory name. Additionally, use '-P' to get the canonical directory name |
31 | # so that Guile's 'relative' %file-port-name-canonicalization can actually | |
32 | # work (see <http://bugs.gnu.org/17935>.) | |
