icedtea6-1.9.3 Build Problem: NoClassDefFoundError: org.apache.xerces.dom.DeferredDocumentImpl

[tjoen]

Hi list,

First time trying to build IcedTea.
System: Linux-x686 from sources (inspired by LFS)
icedtea6-1.9.3 (same problem with 1.9.2)
gcc-4.5.1
xerces-2.11.0

Below is the problem I encountered:

What could be the problem?
