I think the problem comes from your use of -Xbootclasspath to set the  
classpath, which actually configures the bootsrap class loader.

The NPE (at net.sf.saxon.Configuration line 231) comes from the line:
Configuration.class.getClassLoader().getResourceAsStream(sConfigFile);

The Javadoc for #getClassLoader says that "Some implementations may  
use null to represent the bootstrap class loader" [1]
see http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Class.html#getClassLoader()

You should try using the "regular" classpath option:

java -cp $CLASSPATH com.xmlcalabash.drivers.Main $@

HTH,
Romain.
