hmm - maybe, maybe not.  The feature was from this change:

20111008
        + modify misc/gen-pkgconfig.in to use Requires.private for the parts
          of ncurses rather than Requires, as well as Libs.private for the
          other library dependencies (prompted by Debian #644728).

I'd likely overlooked this because (to avoid interfering with Debian's
packages) have generally put my test-libraries in /usr/local, and used
rpath to help that.  However I might have stumbled over it "soon" since
I'm in the process of reworking the test-package to put it in /usr (and
not need rpath...).

I'm puzzled why you've run into this problem at this point in time (unless
it's some issue with the way my reworking is progressing...)
