# Instructions at

# say
#   ln -s /usr/local/lib/slib /usr/local/share/guile/2.0/slib
# However, slib's default catalog location is guile/site/2.0, so we
# use that.

# There is a residual problem where after slib is used (and scheme
# code is compiled), building the package again can result in "Unbound
# variable: module-export-all!".

INSTALLATION_DIRS=	guile/${GUILE_DIR}/share/guile/site/${GUILE_DIR}

# GUILE_LOAD_PATH enables (ice-9 slib) to find slib, needed because
# the symlink is in the DESTDIR but not yet in the installed system.
# GUILE_IMPLEMENTATION_PATH is an override to the slib catalog build
# procedure to write the catalog at that particular path instead of
# the default value of (%site-dir), which is
# /usr/pkg/guile/2.0/share/guile/site/2.0
# The RM commands are only needed if there is a failure in install and
# install is re-run.
