All,
I am trying to use "emerge -uDN world"  to upgrade from an older snapshot to 20081008 and I cannot seem to get past the issues with module libxml2.
I have tried running python-updater -p and it complains about blocked packages which are older packages that I have not yet been able to get updated via the  emerge world.
Is it possible to do an emerge -uDN to the latest snapshot on a system that was built a year or two ago or do I have to do it in stages?
If so what is the correct procedure?
The following is a snipit of the failure and it does not only happen with epiphany.


if [ -f "C/epiphany.xml" ]; then d="../"; else d="/var/tmp/portage/www-client/ep
iphany-2.22.3/work/epiphany-2.22.3/help/"; fi; \
        (cd es/ && \
          `which xml2po` -e -p \
            "${d}es/es.po" \
            "${d}C/epiphany.xml" > epiphany.xml.tmp && \
            cp epiphany.xml.tmp epiphany.xml && rm -f epiphany.xml.tmp)
