[MapProxy] Mapnik render error - proj_create: init=epsg:/init=IGNF: syntax not supported in non-PROJ4 emulation mode

[Phillip Ashworth]

Hi,
I’m new to MapProxy and I’m trying to get a very basic setup running 
with a mapnik source.

I have Mapnik working successfully with Apache and mod_tile/renderd but 
when I try to generate tiles via the MapProxy demo app I get the 
following errors:


```

```

I’m running mapproxy-util with config below:

# mapproxy-util serve-develop -b 0.0.0.0:8080 mapproxy.yaml


```
services:
   demo:
   tms:
     use_grid_names: true
     # origin for /tiles service
     origin: 'sw'
   kml:

       bbox_srs: 'EPSG:27700'
       origin: 'sw'

globals:

```

I’m not sure if this is an error on my part in configuring MapProxy or 
an incompatibility between the versions of Mapnik/MapProxy (Mapnik 3.1.0 
with the latest MapProxy).

Any help would be much appreciated.
