Installing libspatialite package with Homebrew on OS X and using
django.contrib.gis.db.backends.spatialite as a database backend, I met
this exception:

}}}
On Homebrew's SpatiaLite 4.2.0 package what I've got, it provides both
libspatialite.7.dylib and mod_spatialite.7.dylib. For its proper working,
sqlite3 should load mod_spatialite instead of libspatialite, but it seems
not detecting right package with ctypes.util.find_library('spatialite').
In case using find_library('mod_spatialite'), it does work.

p.s: For sure, you can avoid this by declaring sptialite library path
manually in settings.py, like as:
{{{
SPATIALITE_LIBRARY_PATH='/usr/local/lib/mod_spatialite.dylib'
}}}

Comment:
I think it'd probably be better to include a note in the documentation
about this (suggest using the setting) rather than hardcoding a workaround
in Django for what appears to be a non-standard library name.

Agreed. But I have no idea where I begin to work on - for this is my first
contributing on django - , may I ask you few questions?
- I think this document url is right position to start, you know, it's
sort of outdated. Is it better to leave contents for older version
(KyngChaos packages and its SpatiaLite version is 2.3.1, current
SpatiaLite version supported by Homebrew is 4.2.0), or get rid of them?
What do you think?
https://docs.djangoproject.com/en/1.7/ref/contrib/gis/install/spatialite
/#spatialite-macosx
- Is it same way updating document with posting codes with pull requests?
(specifically, commiting to path /docs on Django repo)

Comment (by timgraham):
Some updates to the Mac OS X instructions would be welcome. We can likely
remove the older out-of-date information.
Yes, contributing to the docs is the same process as making code changes.
