I have created what I call a 'white site' - Its sort of a mix of CWS, Blog4Umbraco & other things I have added on.  I now want to package this up, so when I start a new site I can load this package and I'm ready to roll.

Now everything is working fine apart from the Blog4Umbraco - Its having errors loading certain XSLT files, and if I visualise the XSLT I get an error like so

System.Xml.Xsl.XslTransformException: Cannot find the script or external object that implements prefix 'urn:tagsLib'.

I'm missing this

urn:tagsLib

I must have missed this when I packaged everything up, but I have no idea where to find / re-implement it?  Any ideas?
