fontconfig @ 2.13.0 : configuration error

[beechbrandt]

I'm getting an error with a fontconfig upgrade which came about from doing a "port upgrade outdated". The fontconfig configure step is failing with an error like:

configure:16976: checking for a usable iconv

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

Alternatively, you may set the environment variables FREETYPE_CFLAGS
and FREETYPE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
