Huh... After I posted my question, I googled it w/o any reference to
sage and I found that this is a python module warning. But installing
the python service-identity module did not work. First I tried
installing it via apt-get:
$ apt-get install python-service-identity
Same warning. Then I tried to install it via pip:
$ pip install service-identity
Requirement already satisfied.
Looks as if the apt-get actually did install the python module. When I
did what you suggest:
$ sage -pip install service_identity
That fixed it. So I guess sage has it's own version of python?

The command
$ ./sage -pip install service_identity
will install the module in question for you. This calls pip, a standard
Python package
manager, which will fetch the code from the appropriate repository
(<https://pypi.python.org/pypi/service_identity

in this case) and build/install it.
Sage components, things you can install by doing
./sage -i
are sometimes also Python modules, but often are not.
HTH,

What is a sage module? Is that the same as a plugin? I'm getting an
error that says the service_identity module is missing. It has some
directions for getting rid of the error message but I don't want to
mess
with it if I don't have to. I maintain a sage installation for
approximately 100 machines and I want the installation to be as routine
as possible.
Right now, for each installation, I simply do the configure, make, and
then "for PLUGIN in `sage -optional | grep not_installed | cut -d' '
-f1`; do sage -i "${PLUGIN}"; done. In other words, I compile sage and
then all the plugins. But after doing this for sage 7.6, I started
getting the error message reproduced below. If I could make it go away
by no installing one of the plugins, I'd probably just do that.

Twisted can perform only rudimentary TLS client hostname verification.
