Thank you for the very fast response—excuse my slowness, caused by not
setting up email alerts properly.
Starting with last question first, the Python library/executable files:
1. Python / 'libpython2.7.so'
======================

2. SDKs
=======
My mac (OSX 10.11) has 3 SDKs installed after multiple OS X and XCode
updates:
- /Developer/SDKs/MacOSX10.5.sdk/
- /Developer/SDKs/MacOSX10.6.sdk.hide/
-
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/bin/apr-1-config
Note the '.hide' appended to the 10.6 SDK. Compilation of mod_wsgi-express
didn't work until I did that. 10.6 is only there in response to an earlier
Canopy issue. I installed it in Mavericks after seeing this Canopy support
post
<https://support.enthought.com/hc/en-us/articles/204469410-OS-X-GCC-Clang-and-Cython-in-10-9-Mavericks>
.
