Here is my output from load_gdml

[wattsjw@watts G01]$ load_gdml matricesandloops.gdml

Usage: load_gdml <intput_gdml_file:mandatory> <output_gdml_file:optional>

G4GDML: Reading 'matricesandloops.gdml'...
G4GDML: Reading definitions...
G4GDML: Reading materials...
G4GDML: Reading solids...

I am using CLHEP.2.0.4.2 and xerces-c-3.0.0 on an Operron running Scientific Linux 5.1.

Attached is matricesandloops.gdml taken from GDML_2.1.10.0/CPPGDML/Examples/g4g0gdml. It was modified to point the the geant4.9.2 gdml schema.
