 I can not reproduce Paul's problem and I get similar output to Mark's:

 HINT:  PostGIS was unable to transform the point because either no grid
 shift files were found, or the point does not lie within the range for
 which the grid shift is defined. Refer to the ST_Transform() section of
 the PostGIS manual for details on how to configure PostGIS to alter this

 I use GEOS and PostGIS built from SVN trunk today morning on Linux Ubuntu
 9.10 (64-bit)
