I think the problem is related to ASDF, as described in
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723977>.

ASDF searches for .asd files inside some directories and trees,
including the ones described by `XDG_DATA_DIRS'.  When `XDG_DATA_DIRS'
is empty or not set, `/usr/local/share:/usr/share/' should be used,
which is not occurring.
