This version is not yet released,
You could use the current SVN version from 1.3 branch:

svn checkout http://svn.refractions.net/postgis/branches/1.3 postgis-1.3

(require to have an svn client already installed, cf http://subversion.tigris.org/)

Not sure to really understand the question, below a working use case:

SELECT ST_AsGeoJson(the_geom) FROM your_table LIMIT 1;

and copy/paste the result in OpenLayers:
