a couple of failure on running "make test" over XML-Xerces-2.3.0- 4

Hi, 
I built XML-Xerces-2.3.0-4 using gmake successfully, after successfully
built and installed xerces-c-src_2_3_0 in solaris 8 environment, but when I
run the gmake test I got the following result that a couple of the tests
failed. Does Anyone have an idea on that? Is this a serious problem? Is
there any impact on the applications based on the Xerces module, if I just
do "gmake install" to install it?

Thanks,
Wei Lu
