Are you building a 32 or 64 bit target? What is your complete configure 
command line?

I notice that freetype was found using pkg-config, but FREETYPE_LIBS is 
only "-lfreetype". That is weird, and possibly a bug in the pkg-config 
description of freetype on Ubuntu 13.10. As comparison, on my ancient 
Ubuntu 11.04, FREETYPE_LIBS gets set to "-L/usr/lib/x86_64-linux-gnu 
-lfreetype".

Did the build work properly before? That is, not only that configure 
accepted your freetype installation, but that the resulting build 
actually could link with freetype at runtime? Otherwise, this might be a 
case of "failing fast" in configure, rather than a bug.
