Yes, on OS X, but it wasn't easy, and it didn't bootstrap for me due to SSL errors. Others have had more luck, but mostly on Linux AFAIK.

Do you perhaps have a system-installed OpenSSL 0.9.* which is lacking EVP_aes_128_ctr?

See https://trac.torproject.org/projects/tor/ticket/13817 for a similar failure, due to the following issues:

configure --with-openssl-dir= detects the wrong bin/openssl if "$OPENSSL_DIR/bin/openssl" isn't in the path before all other openssl executables.
configure --enable-static-openssl requires LDFLAGS="$OPENSSL_DIR/lib":$LDFLAGS to link properly, at least on OS X.

If you do run into runtime SSL errors, see this bug:
https://trac.torproject.org/projects/tor/ticket/13816
