P. S. If someone cares about this working on older macOS, pick fixes from macos-powerpc/powerpc-ports@2772b2b

P. S. Let me check if those flags are still relevant.
Upd. Flags that I had in my portfile to downgrade errors to warnings are NOT needed with 0.10.2.

P. P. S. The port was submitted earlier in #29634

@trodemaster Since MacPorts supports "older" platforms, there are more changes you should take into account given @barracuda156's suggetion. Tested on macOS 10.7.5 11G63 x86_64 Xcode 4.6.3 4H1503.

Essentially

• Add the legacysupport PortGroup in order to link with MacPorts's clock_gettime on older systems, particularly on macOS 10.11 and older.
• Limit which compiler is used when building. This is often done by setting a standard, but there are times in which this is not sufficient. clang < 700 do not build the project, so they need to be blacklisted.
