And libxml2.dll is placed in

C:\Program Files\Rational\Common\libxml2.dll
[download]

i hope this could throw some light!

I'm afraid I'm a bit stumped - everything above looks OK. Just to see if it might be a binary incompatibility problem with your version of Perl, could you try installing the GD module; the ppm sources GD.tar.gz are again at http://theoryx5.uwinnipeg.ca/ppmpackages/x86/. After installation, does

   C:\> perl -MGD -e "print 1"
[download]

work?

tried and got this

the common.dll is present in C:/Program Files/Rational/Common/lib/perl5/site_perl/5.6.1/MSWin32-x86-multi-thread/auto/XML/LibXML/Common/ folder

Also i tried placing the libxml2.dll in the same folder as common, but still i get the same error!
