Problem compiling librsvg on NetBSD 8.1

[Mike Pumford <mpumford%mudcovered.org.uk@localhost>]

Just ran into this error trying to compile the latest librsvg on 8.1 
AMD64 with the native Xorg.

Package dependency requirement 'freetype2 >= 20.0.14' could not be 
satisfied.
Package 'freetype2' has version '18.0.13', required version is '>= 20.0.14'

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBRSVG_CFLAGS
and LIBRSVG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
*** Error code 1

Suggestions? Modular Xorg isn't really something I want to entertain to 
solve this problem as it will make my already long pkgsrc builds even 
longer.
