perl Maefile.PL fails because of version incompatibility

I just downloaded the Xerces-C.2.6.0 (the current/latest) version.
I also downloaded the current/latest version of XML-Xerces-Perl
(2.5.0).

Trying to make the perl version but get the following error.

You are attempt to build XML::Xerces-2.5.0-0 using Xerces-C-2.6.0,
this will most likely fail, so I am aborting.

You must use Xerces-C-2.5.0

 Where can I find the Xerces-C.2.5.0 (serached the xml.apache.org) but could
not fidn the source code distribution for this version which I could 
download
and build.

I will appreciate any help or pointers to the C-2.5.0.
