FT_New_Face failed: cannot open resource

I've compiled TA Spring (which is a whole story in itself) because they don't provide Mac binaries. Anyway, now when I try to run it I get the following errors:

Code:

---

Warning: Incorrect/Missing content:
  FT_New_Face failed:cannot open resource

SpringRTS has exited with status 255.

I compiled Freetype from source (which may be the problem), and added libfreetype.dylib to my project. Can anyone tell me what it's trying to open? Or do I need to provide more information?
