My apologies for not clarifying.

You will need to add the repository, as described in my post, to your repository list in application manager. Alternatively, you may manually edit sources.list yourself, but I would not recommend this.

Afterwards, gain root and execute 'apt-get install libglade' at which point you should be able to run abiword.

The line about only using it in scratchbox refers to the fact that adding it to a running i386 debian-based installation will cause Hildon libraries to be installed on a non-hildon PC. This would cause a few issues
