py-grpcio: various buildbot failures

[mascguy (Christopher Nielsen)]

There are a few different issues with this port build, depending on the platform.

The following is what we're seeing for the latest buildbot jobs:

Big Sur x86_64:

​https://build.macports.org/builders/ports-11_x86_64-builder/builds/31390/steps/install-port/logs/stdio

distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET mismatch: now "11.0" but "11.2" during configure

10.6:

​https://build.macports.org/builders/ports-10.6_x86_64-builder/builds/57438/steps/install-port/logs/stdio

error: invalid argument '-std=c++11' not allowed with 'C'

For 10.7 through 10.9:

​https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/53892/steps/install-port/logs/stdio

​https://build.macports.org/builders/ports-10.8_x86_64-builder/builds/47452/steps/install-port/logs/stdio

This might be a case of blacklisting older clang versions, and perhaps blacklisting Xcode clang entirely (if necessary).

[mascguy (Christopher Nielsen)]

Some of these might be fixable with compiler blacklisting.

But others might relate to our portgroups. CJones, any thoughts/ideas?

[cjones051073 (Chris Jones)]

can you attached a complete logs ?

[mascguy (Christopher Nielsen)]

These are all from buildbot jobs that ran within the last 10 minutes, grab them from the waterfall display.

[cjones051073 (Chris Jones)]

I'm on a mobile device and thats not so easy. It would be useful to have parma-links to these logs here as in time they will be hard to find.

[mascguy (Christopher Nielsen)]

Added links to specific buildbot jobs

[mascguy (Christopher Nielsen)]

Attached full logs from the various buildbot jobs, so that they're not lost when build history ages out.

[mascguy (Christopher Nielsen)]

I'll take a look at fixing the builds on 10.6 through 10.9.

CJones/anyone, thoughts regarding the Big Sur failure ($MACOSX_DEPLOYMENT_TARGET mismatch: now "11.0" but "11.2" during configure)?
