[pdal] Build pdal with python 3

[FE]

To my knowledge gcc on OS X is not gcc. It's a link to Apple LLVM which has a different versioning than original LLVM.
Here is the output for compiler versions on my machine:

mac:~ me$ clang --version
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin14.5.0
Thread model: posix

mac:~ me$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin14.5.0
Thread model: posix
 

The GCC 4.2.1 reporting which you refer to is a reporting from python. At least to my understanding it means a GCC 4.2.1 compatibility of the Apple LLVM:

mac:~ me$ python
Python 2.7.11 (default, Dec  5 2015, 14:44:47) 
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.1.76)] on darwin
Type "help", "copyright", "credits" or "license" for more information.



My machine is from 2015, has OS X 10.10.5 and up to date XCode. It has never seen something older. So I assume that I work with the original and most up to date Apple compiler.
I am not the most advanced expert in compilers and building software. But I would just like to receive some support in solving this python problem when building pdal. Docker is not an option for me.

Thanks,
Will

Your compiler is reporting GCC 4.2.1, which is from 2007.  We just don't support compilers that old and things may or may not work in lots of ways.  You can use our docker image if you can't upgrade compilers or find a suitable binary.
