difficulty installing pystan

[Noah Motion]

I've gotten pystan to install and function properly on two Macs (one iMac, one Macbook Air), both running Yosemite. I tried to install it on a third Mac, also running Yosemite, and got this error:

error: Command "gcc -fno-strict-aliasing -I/Users/noahsilbert/anaconda/include -arch x86_64 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -DBOOST_RESULT_OF_USE_TR1 -DBOOST_NO_DECLTYPE -DBOOST_DISABLE_ASSERTS -Ipystan/stan/src -Ipystan/stan/lib/eigen_3.2.0 -Ipystan/stan/lib/boost_1.54.0 -c pystan/stan/src/stan/agrad/rev/var_stack.cpp -o build/temp.macosx-10.5-x86_64-2.7/pystan/stan/src/stan/agrad/rev/var_stack.o" failed with exit status 69

I am at a loss to understand what this means or what I can do to get pystan to work on this computer. Any advice would be greatly appreciated.

Hi Noah,

I'll take a stab at figuring this out. Are you doing ``pip install pystan`` from
within an Anaconda environment? Could you post more of the error? (posting it on
github would be ideal too).

Thanks,

Allen, thanks for being willing to help out. Yes, I am using Anaconda, and I tried 'pip install pystan --upgrade' (since I had an older version installed). (And I should have given that information in the first place, too - sorry!). I've attached the log file that pip pointed me to after the installation/upgrade failed. As far as I can tell, all the error messages are at the end, but there may well be useful information elsewhere in the file.

Somehow I had missed that it was telling me I hadn't agreed to the Xcode license on this computer, so I've now done that and am trying to upgrade again. Hopefully this will work...

EDIT: And it worked. Thanks again for being willing to help out. Sorry to have wasted anyone's time on this.

Allen,

And now I'm having difficulty with a different computer. This one is a Mac Pro with Yosemite and Anaconda, and I didn't have an older version of pystan installed already, so I tried 'pip install pystan' and got the following error message (it's not telling me where, if anywhere, there is an error log, and I can't find anything after poking around for a few minutes):
