Error with plpython

Hello.

Strange thing happening:

We rencently installed plpython in one of our test servers and installed an extension to use the google api (http://pypi.python.org/pypi/googlemaps ) , everything went fine we tested this function:

CREATE OR REPLACE FUNCTION google_reverse_geocode(lat numeric, lon numeric)
RETURNS text AS
$BODY$

from googlemaps import GoogleMaps
gmaps= GoogleMaps()
address = gmaps.latlng_to_address(lat,lon)
return (address)
$BODY$
LANGUAGE plpythonu VOLATILE
COST 100;
ALTER FUNCTION google_reverse_geocode(numeric, numeric)
OWNER TO pgsql;

However, once we installed it on our production server that function doesnt work, it keeps sending this message:

ERROR: ImportError: cannot import name SSLError
CONTEXT: Traceback (most recent call last):

The strange thing is that our server are the same in everything so we don’t know why is failing in our production eviroment.

Thanks in advance.
