Why are devel/py-setuptools missing -I${LOCALBASE}/include ?

Standard warning first up: use of pip install as root (without --user)
to install third party packages directly into the system site-packages
environment is completely unsupported, and *will* break the python
environment if mixing with ports/packages. The pkg-message for
devel/py-pip contains this warning too.

No. `pythonX.Y-config` on the other hand (provided by each lang/python??
port) can provide the *FLAGS that the python environment was built
in/for, *if* a consumer chooses to use it. However, this is most often
used only by non-Python-library softwares that want to depend on the
python shared library.

The options from here, depending on the specific package are:

- Try CFLAGS/LDFLAGS to pass the -I/-L paths.
- Try using the --include-dirs, --libraries and --library-dirs (-L)
arguments to the setuptools build_ext command (see pythonX.Y setup.py
build_ext --help for more)

Or, just use the net/py-ldap0 port [1], which already does the right
thing (it appears the ldap0 package uses a non-standard INCLUDE variable
to pass things into it)

Hope that helps. If you have questions and need any more help, we're
always available on #freebsd-python on freenode IRC if you need us.
