At first I agreed with you, but after looking a little more I think I have been using the same one all along,
and it just changed.  Perhaps this is just an early warning. Or perhaps my X11 is old and stale.

I don't know what your basis for "it seems unlikely" is.
I did not set --with-freetype, so to me it appears not only likely, but certain, that it picked that up by itself.
(I think I would have mentioned this....)

I looked at the logs from the old build, and they appear to be identical to the logs with the symbolic link
added, since I did not touch the flags.  It's "unlikely" (that word again) that adding the link would change
things, since it made the mistake without the link and the added link merely causes the build to succeed.

I thought the preferred mode was for configure to work properly without human intervention :-).

dr2chase:~ dr2chase$ pkg-config --cflags freetype2
-I/opt/local/include/freetype2 

dr2chase:~ dr2chase$ ls -l /opt/local/include/freetype2/freetype
lrwxr-xr-x  1 root  admin  12 Jan 31 15:35 /opt/local/include/freetype2/freetype -> ../freetype2

dr2chase:~ dr2chase$ sudo rm /opt/local/include/freetype2/freetype
Password:

dr2chase:~ dr2chase$ pkg-config --cflags freetype2
-I/opt/local/include/freetype2 

dr2chase:~ dr2chase$ 

But....

dr2chase:~ dr2chase$ which pkg-config
/opt/local/bin/pkg-config

That looks like a likely cause, but that appears to be the only pkg-config on the box.
(Checked /bin, /usr/bin, /usr/local/bin, /etc, /usr/etc, /usr/sbin, /sbin )

Was my mistake installing freetype?  Lots of stuff depends on it:

R depends on freetype
Xft2 depends on freetype
cairo depends on freetype
dvipng depends on freetype
fontconfig depends on freetype
gd2 depends on freetype
