Both textproc/py-sphinx18 and textproc/py-sphinx require
the following to have been built and installed already
in order to build:

lang/python37
devel/py-setuptools at py37

textproc/py-sphinx18 requires 3 more ports as well:

devel/py-Jinja2 at py37
textproc/py-docutils at py37
devel/py-six at py37

Some building and isntalling had to occur prior to the
textproc/py-sphinx18 build attempt, possibly from
prior session(s) of building and installing.


textproc/py-sphinx18 is new as of 2020-May-11.
The devel/llvm[16789]0 ports require textproc/py-sphinx18 .
Only about 26 ports require textproc/py-sphinx18 but
I'll not list the others.

textproc/py-sphinx has been around longer and has
142 ports that require it. I'll not list them.


textproc/py-sphinx18/Makefile lists:

CONFLICTS_INSTALL=      py*-sphinx

textproc/py-sphinx/Makefile lists:

CONFLICTS_INSTALL=      py*-sphinx18


So, for example, indirectly the devel/llvm[16789]0
ports conflict with at least 142 other ports because
of the textproc/py-sphinx* difference in requirements.


The conflict is real and limits what combinations
of ports you may have installed at the same time.
