W3C validator : SGML Parser - OpenSP module

Hi Team,

For W3C validator, the given explanation and steps to follow are very good at http://validator.w3.org/docs/install.html, I started work on windows with this information. Everything went very well until I got into SGML parser issue.

Unable to make 'OpenSP.dll' it is causing the below issue, Could you please share OPENSP.dll  file or guide me what needs to be done.

Can't locate loadable object for module SGML::Parser::OpenSP in @INC (@INC contains: C:/www/perl/site/lib C:/www/perl/lib .) at C:/www/validator/httpd/cgi-bin/check line 65.
Compilation failed in require at C:/www/validator/httpd/cgi-bin/check line 65.
BEGIN failed--compilation aborted at C:/www/validator/httpd/cgi-bin/check line 65.

When I try to 'perl Makefile', getting below prompts to give linking library and compiler to use. However i do not have much knowledge on Perl, so I am not sure how I can get it resolved. I have downloaded osp152.lib from OpenJade, but it doesn't seem to be working fine.

C:\www\ppm\SGML-Parser-OpenSP-0.994>perl makefile.PL
Set up gcc environment - gcc.exe (gcc-4.6.3 release with patches [build 20121012
 by perlmingw.sf.net]) 4.6.3
Where is the OpenSP link library? [T:\osp\lib\Release\osp152.lib]  ??????
Which compiler should be used? [cl -TP -EHsc -IT:/osp/]  ???????

Expecting you guidance at the earliest. Thanks in advance!!!

Thanks and regards,
Kiruthika
