Did you install postgis from sources ?
Did you run "make check" before installing ?  Did it succeed ?

Find your postgis-2.0.so file, run `ldd <postgis20_so>` on it and see if you
get any not-found message and if you get a libjson link line.
Then run `nm <libjson_file>` and see if you get any
``json_tokener_errors`` line
