Comment (by kencu):

 I have this working on the last MacPorts version back to 10.6.8 without
 any trouble.
 {{{
 $ port -v installed librecad
 The following ports are currently installed:
   LibreCAD @2.0.8_2 (active) platform='darwin 10' archs='x86_64'
 date='2018-05-21T15:30:16-0700'
 }}}
 I'll update it to the current release version and set up a PR for you
 shortly.
