It's unlikely to be resolved unless it's reported, and this is the
first I'ver heard of the problem in quite some time as I thought we
fixed it.

You could start by showing the relevant part of config.log, so we
could see why the test fails.

As I recall, I used to have to add

  -I/usr/include/freetype2

to CPPFLAGS on my system when running configure, but I think we fixed
that problem as it no longer seems to be required.

Simply posting this vague information does not help much.  It works
for me.  How did you install them?  Can your compiler find them
without special flags?  If special flags are needed, are you passing
them to configure in some way?  How?
