booktabs-de from texlive-lang-german not installed in debian wheezy

I have debian wheezy with packaged texlive (TeX Live 2012/Debian) and want to use the package booktabs-de from the apt-package texlive-lang-german. The debian apt installation of that package ran fine.
I'm wondering, why it is not really installed (into the tds). Please have a look at those lines
apt-file show texlive-lang-german | grep  booktabs
texlive-lang-german: /usr/share/doc/texlive-doc/latex/booktabs-de/README-DE
texlive-lang-german: /usr/share/doc/texlive-doc/latex/booktabs-de/booktabs-de.dtx.gz
texlive-lang-german: /usr/share/doc/texlive-doc/latex/booktabs-de/booktabs-de.ins
texlive-lang-german: /usr/share/doc/texlive-doc/latex/booktabs-de/booktabs-de.pdf
texlive-lang-german: /usr/share/doc/texlive-lang-german/latex/booktabs-de/README-DE
texlive-lang-german: /usr/share/doc/texlive-lang-german/latex/booktabs-de/booktabs-de.dtx.gz
texlive-lang-german: /usr/share/doc/texlive-lang-german/latex/booktabs-de/booktabs-de.ins
texlive-lang-german: /usr/share/doc/texlive-lang-german/latex/booktabs-de/booktabs-de.pdf
meaning the package contains it - but it is not installed as the following lines show:
find / -name 'booktabs*.sty'
/usr/share/texlive/texmf-dist/tex/latex/booktabs/booktabs.sty
Okay, I can run the .ins-file and move the results - but shouldn't that be done already by the installer? Is this a debian bug? If, feel free to move this question into the right forum. Thanks.
