I now have texlive-base 2009-6 installed (as suggested by #561785).
    - v0.47 2009-10-12 as per /usr/share/doc/texlive-base/texdoc/texdoc.pdf
    - v.0.6.0a (Nov 5, 2004) as per /usr/share/texmf-texlive/scripts/tetex/texdoctk.pl

Out of the box it doesn't work.

It works perfectly if I manually enable support_zipped=true in the
new script (/usr/share/texmf-texlive/scripts/texdoc/constants.tlu). It
allows me to view compressed docs, like pgfmanual.pdf.gz from texdoc
pgfmanual.

Without this manual intervention, it doesn't work.

The problem comes from default config file locations. Running texdoc
with -d, I can see that no config files are found:
    texdoc debug-files: Configuration files are:
    texdoc debug-files: absent      /home/jst/texmf/texdoc/texdoc-bin.cnf
    texdoc debug-files: absent      /home/jst/texmf/texdoc/texdoc.cnf
    texdoc debug-files: absent      /home/jst/texmf/texdoc/texdoc-dist.cnf
    texdoc debug-files: absent      /usr/local/share/texmf/texdoc/texdoc-bin.cnf
    texdoc debug-files: absent      /usr/local/share/texmf/texdoc/texdoc.cnf
    texdoc debug-files: absent      /usr/share/texmf/texdoc/texdoc.cnf
    ...

However, texlive-base installs texdoc.cnf here on my system:
    /usr/share/texmf-texlive/texdoc/texdoc.cnf

This file does have the correct support_zipped=true configuration and
viewing compressed docs would work fine if it was considered, moved or
linked in the right location.
