Plone Document Files Management Products

Would like to install

http://plone.org/products/arfilepreview

http://plone.org/products/arofficetransforms

which provide the ability to index and preview a variety of file formats including

MS Office, OpenOffice,  PDF, ZIP format on Plone.

However, I need help install GNU/Linux-based binaries for

• ppthtml
• xlhtml
• wv
• xlstproc
• unzip
• pdftohtml

According to the book Plone 3 Intranets: https://www.packtpub.com/plone-3-design-build-deploy-full-featured-secure-enterprise-intranet/book

We should use the following command for ubuntu-based server

> sudo apt-get install ppthml xlhtml wv xltproc unzip popplex-utils

Other references can be found here: http://pypi.python.org/pypi/Products.AROfficeTransforms

My question is which sub-directory should the binaries be installed to.
