I use it. Works fine for me (on 64bit, FreeBSD-CURRENT).

This results for me in a shell script /usr/local/bin/dylan-compiler,
which does:
export LD_LIBRARY_PATH="/usr/local/lib/opendylan/lib"
exec /usr/local/lib/opendylan/bin/dylan-compiler "$@"

I also run make 3-stage-bootstrap (with some magic to configure to
find the path to boehm-gc; using a git checkout from 20th December,
698edf9810a437505d7ec85a7736691a3291c74a), resulting in a
/usr/local/opendylan-2013.2/bin/dylan-compiler:
/usr/local/opendylan-2013.2/bin/dylan-compiler: ELF 64-bit LSB
executable, x86-64, version 1 (FreeBSD), dynamically linked (uses
shared libs), for FreeBSD 11.0 (1100002), not stripped

It does work for me fine on 64 bit.

I think this was the case for 2013.1, but is no longer in newer versions.

Haven't actively used the HARP backend since a while on FreeBSD (and
not 32 bit at all)..
