--------------------------+--------------------
 2.1.1 was released in 2018. Current version in MacPorts is 1.6.1, released
 in 2005, and has a known security vulnerability (CVE-2018-1000632).

 Port currently has fallback dependency on deprecated port `kaffe`, which
 should be replaced with using the Java portgroup: #60206.

 (I personally do not need this port. I had proposed deleting it:
 https://github.com/macports/macports-ports/pull/5112, but there is
 disagreement over deleting ports still maintained upstream.)
