it depends on how FreeType was compiled. By default, it no zlib is found 
by the "configure" script,
the font engine will include its own copy of the zlib decompression 
routines, and no "-lz" will be
required at link-time. Another option is to build the library without 
its "gzip" module at all, but
I doubt that was the case here.

so a missing "-lz" in 'pkg-config --libs freetype2' doesn't necessarily 
means a problem here.

Hope this helps,
