Comment 2 for bug 448549

This is harder one to work around than what I original thought it be.

Rather than tweaking debconf, this package is installed via a hard-coded line in the Ubiquity installer.

That makes the possible solutions:
1) Just advise English users to press 'Skip' when it comes up about Language Support
2) Rebuild the language-support-en package, or one of it's dependencies (that pulls in openoffice) to NOT depend on it.
3) Remove or comment out line 1348 from /usr/share/ubiquity/install.py so it looks like this:
            # More extensive language support packages
            #to_install.append('language-support-%s' %lp)

I'm in favour of option 3, as it is the least amount of hassle.
