[postgis-users] PostGIS 2.0.1 build results in ".../postgis-2.0.so: undefined symbol: json_tokener_errors"

[Bborie Park]

Try running...

ldd postgis-2.0.so

That'll tell you if postgis can't find the json lib.  If it can't, try...

nm libjson.so | grep json_tokener_errors

You may need to try libjson-c.so instead.  If the grep doesn't find
json_tokener_errors, something is up...
