LibreCAD: g++-mp-4.8: error: unrecognized command line option '-arch'

[ryandesign (Ryan Carsten Schmidt)]

LibreCAD fails to build on OS X 10.8 and earlier with:

g++-mp-4.8: error: unrecognized command line option '-arch'

What is going on here? Why does the port force the use of gcc48 on 10.8 and earlier? That's super strange.

I see the build uses -std=c++11. If the use of gcc48 was an attempt to provide a C++11-compatible compiler, please just include the cxx11-1.1 portgroup and let it handle these details.

At the time more than a few moons ago... I don't think we had a cxx11-1.1 option but educate me if that was the case. If I remember correctly, and it's been a while.... 10.8 support was needed for us and we only had one test machine (virtualised) to test it on. It wasn't easy to make all builds work....

We can drop support of 10.8...

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.
