--- Comment #13 from Kubilay Kocak <koobs at FreeBSD.org> ---
(In reply to Fukang Chen from comment #10)

Escalating to portmgr@ (see below)

@portmgr please advise if/what workarounds might be available to python@ to
resolve the issue in lang/python* ports until the root cause can be fixed
permanently.

@Fukang, can you include that test matrix (pastebin) as an attachment so it
doesn't get lost (or missed) please.

Notes:

The CFLAGS modification workaround is not a root-cause fix, as it doesn't
resolve the expected/actual runtime library discrepancy (uses base, not ports).

To be clear, it appears thus far from the evidence provided, that this is the
result of a conflict caused by the interaction between framework ncurses/ssl
bits, relating to base vs ports rpath arguments, exposed by the move from
Mk/bsd.foo.mk to Uses/foo.mk. It also appears that this is not strictly, or in
principle limited to python, nor ssl and ncurses only, but has a much wider
potential for impact.

Q: What other existing base vs ports cases could highlight the same issue?
Q: Does swapping ssl/ncurses in USES not just reverse the problem in the case
of base ssl and ports ncurses? If not, why not?
