[postgis-users] 2.1.0beta3dev upgrade error

[Stephen Woodbridge]

Hi all,

I just tried to upgrade postgis from 2.0.3 -> 2.1.0beta3dev and got the 
following error:

pgr_test=# alter extension postgis update to '2.1.0beta3dev';
ERROR:  could not load library 
"/usr/lib/postgresql/9.2/lib/postgis-2.1.so": 
/usr/lib/postgresql/9.2/lib/postgis-2.1.so: undefined symbol: 
json_tokener_errors

Did I forget a step or do something wrong?
