JSON-C for PostGIS

[johnernaut]

I'm trying to use the nanobox Postgres image with the PostGIS extension, but in order to use GeoJSON I need PostGIS to be installed with the following flag: ./configure --with-jsonc=/usr/include. Is it possible to customize the nanobox image to do something like that? If not, can I somehow make my own image to do so?

I get the following error when trying to insert using GeoJSON: You need JSON-C for ST_GeomFromGeoJSON.
