need help on virtual class

[fsshl]

Dear C/g++ experts:

in the process of installing/building path1.2r2, at make stage, I get compile
error about errors:
conflicting return type
overriding 'virtual xercesc_3_1::DOMNode:NodeType xercesc_3_1::DOMNode:getNodeType() const'

plz help
and thanks a lot in advance, Eric(g++4.5.2) on linux2.6.38-10
