Problem building XML::Xerces v2.5.0

Hi,
	 I am trying to build XML::Xerces for perl 5.6.1 and the build
has been failing with the following error messages.

/proj/lang/forte-6.2/SUNWspro/bin/CC -c  -I. -IHandler

2 Error(s) detected.

Given below are the steps that I have followed.

1. built Xerces-2.5 from
source(http://archive.apache.org/dist/xml/xerces-c/Xerces-C_2_5_0/xerces
-c-src_2_5_0.tar.gz) to ~/tmp/xerces-c-src_2_5_0
2. export XERCESCROOT=~/tmp/xerces-c-src_2_5_0
3. cd ~/tmp/XML-Xerces-2.5.0-0 . (this is the dir where I have the
XML::Xerces source)
3. perl Makefile.PL PREFIX=~/my/lib
CC=/proj/lang/forte-6.2/SUNWspro/bin/CC
4. gmake
