Hey there - I did unfortunately miss the initial question, hence I have to do a
bit of guess-work here. Forgive me if that is entirely off.
That flag is not explicitly set by Mesos, as Vinod mentioned. It is however
implicitly done by distutils extraction the cflags out of the existing python
installation. So in the end, Mesos does in fact use that flag at least for the
Python egg compilation.
You can check that by running:
python-config —cflags
I would expect something like the following as the result:
-I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
-I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
-fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe
-fno-common -fno-strict-aliasing -fwrapv -mno-fused-madd -DENABLE_DTRACE
-DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g
-fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE
As you can see, there is this "-Wshorten-64-to-32” coming from and it is used
when building the python egg. As you are using gcc to compile and not clang,
the problem pops up.
If you really have to use gcc, then you will have to install an alternative
Python distribution - I would recommend using homebrew or anything else.
As an alternative, use clang as that is AFAIK fully supported since Mesos
0.17.0.
The simplified compatibility matrix is as follows:
apple-python brew-python
clang X -
gcc - X
Hope that helps. There is some more background on this issue on

cheerio!
