Okay, thanks for the tip; I hadn't seen those pragmas before. I should note
that the header file that is the source of all of the redundant decls warnings
(operations.hpp) has been dramatically changed on opencv's git master; they've
been doing some substantial reorganization, so the problem in 2.4.5 may be
transient. I'll try building against HEAD to see how it looks.

It looks like TPM is taking a look at this one. Opencv 2.4.5 is the first
version I've ever built, so I don't know whether opencv.pc file contents have
changed recently or have never been correct on OSX. fwiw, it looks the same
when I build from HEAD.
