Hi Kenneth,
Thanks for your quick reply. I see that I hit this problem because I am not
using the default profile file provided by Lmod. I think I will update my
profile file to apply the workaround provided by lmod
#
# If MANPATH is empty, Lmod is adding a trailing ":" so that
# the system MANPATH will be found
if [ -z "${MANPATH:-}" ]; then
export MANPATH=:
fi
thanks!
Pablo.
