        case $1 in
        dm-crypt)
-               tools="/bin/blockdev-keygen /sbin/dmsetup /sbin/cryptsetup"
+               tools="$tools /sbin/dmsetup /sbin/cryptsetup /lib/libpopt.so.0"

This won't work, I think? We test for [ -x $tool ] further down
in crypto_check_required_tools(). I think we'd need to change the
test to [ -e .. ] or test separately for libs. Somehow I feel we
should find a better way to test for required libraries though.
Perhaps changing the error reporting in anna-install so that we
could tell if a dependency couldn't be loaded?

cheers,
Max
