It is black listed for pkgsrc.

What does that mean? Does it have to do with this snippet of code in pkgsrc/bootstrap/bootstrap?

# On some newer Ubuntu installations, /bin/sh is a symlink to /bin/dash,
# whose echo(1) is not BSD-compatible.
dash_echo_test=`$bootstrap_sh -c 'echo "\\100"'`
if [ "$dash_echo_test" = "@" ]; then
        { echo "ERROR: Your shell's echo command is not BSD-compatible."
          echo "ERROR: Please select another shell by setting the environment"
          echo "ERROR: variable SH."
        } 1>&2
        exit 1;

The above code is interesting because POSIX XSI conformance requires 'echo "\\100"' to output @. It's also trivial to work around:

    portable_echo() { printf %s\\n "$*"; }
