This is one of those messages that tries to 'raise Awareness'.
To run all of the optional doctests, regardless of their modifiers, we
can use
sage -t -only-optional
Most machines do not have all of the optional packages installed, so
it may be more useful to target a particular package:
sage -t --only-optional=xyz
But this could still skip some xyz-only tests, if their doctesting
directives contain unnecessary modifiers.
I did a search for doctests with '#optional' tags:
cd /path/to/sage-4.5.3.alpha1/devel/sage
grep "sage:" `find doc sage -name \*.px\* -o -name \*.py\* -o -name
\*.rst -o -name \*.sage` | grep "#" | cut -d '#' -f 2- | sed 's/^[
\t]*//' | sed 's/[ \t]*$//' | grep optional | sort | uniq -c | sort -nr

According to the doctesting conventions section of the developer's guide
[1],
"""
Any text after 'optional' is interpreted as a package name. Therefore if
the doctest is marked 'optional: requires chomp', then 'requires' is viewed
as a package name, so the test would only be run by either 'sage -t
--optional f.py' or 'sage -t --only-optional=requires,chomp f.py'.
