> Actually, the error message above appears to stem from my having a
`SAGE_LOCAL/bin` in the `PATH` but not a corresponding `SAGE_LOCAL/lib` in
the `LD_LIBRARY_PATH`. I've fixed this by keeping `SAGE_LOCAL/*` out of
both path variables.

mistaken?
I agree with you 100%. If zn_poly requires Python then we must ensure
Python is built first.
I think this should be a blocker myself, but you are the release manager,
so downgrade it if you wish. There are a number of reports of a system
Python causing build problems, so in some cases actually disabling Python
is necessary (see #9209).
There are two other very trivial fixes to deps which are more cosmetic
than anything else, but worth adding, as they aid clarity. These are #9637
and #9464 and we might as well fix all three at once.
Also, SPKG.txt for zn_poly should be updated to reflect the fact there is
a dependency on Python. That's a minor issue, but one worth addressing.
That is now #9762.
I could make all these changes by around 0100 GMT on Thursday 19th August
if you wanted, or could review them sooner if someone else did them. But
I've got a lot to do this afternoon, and don't have time to fix them right
now. I'm not at home, so don't have my workstation by me, which makes
testing things a bit more difficult.
