Comment(by robe):

 Okay I'm guess the problem might be the default output on endian is
 different and the cunit is taking the default behavior.

 For example try this:


 {{{
 WITH outs As (SELECT 'exp'::text As type,
 '0103000000010000000500000000917E9BA468294100917E9B8AEA2841C976BE1FA4682941C976BE9F8AEA2841B39ABE1FA46829415ACCC29F8AEA284137894120A4682941C976BE9F8AEA284100917E9BA468294100917E9B8AEA2841'::geometry
 As geom
 UNION ALL
 SELECT 'obt'::text As
 type,'00000000030000000100000005412968A49B7E91004128EA8A9B7E9100412968A41FBE76C94128EA8A9FBE76C9412968A41FBE9AB34128EA8A9FC2CC5A412968A4204189374128EA8A9FBE76C9412968A49B7E91004128EA8A9B7E9100'::geometry
 As geom)
 SELECT a.type, ST_Equals(a.geom, b.geom) As is_equal
  , ST_OrderingEquals(a.geom, b.geom) As is_ord_equal , ST_Ndims(a.geom)
 , ST_AsEWKB(a.geom, 'NDR')  = ST_AsEWKB(a.geom, 'XDR') As xdr_geom
 FROM outs As a INNER JOIN outs As b ON (a.type != b.type);
 }}}

 I think the only solution is to change the cunit test to be explicit about
 endianess and not leave it up to the OS.
