Bug#527592: Package xfrac not usable

[Michael Goetze <mgo@hosteurope.de>]

Package: texlive-math-extra
Version: 2007.dfsg.17-1~lenny01

I wanted to \usepackage{xfrac} in my document, so I installed 
texlive-math-extra. However, it failed with a compilation error:

! LaTeX Error: File `template.sty' not found.

After a search on packages.debian.org, I found this file in 
texlive-latex3 and installed that. This gave me two new compilation errors:

LaTeX Warning: You have requested, on input line 28, version
               `2001/07/25' of package template,
               but only version
               `1999/09/28 v0.14 template parsing (DPC,FMi)'
               is available.

(/usr/share/texmf-texlive/tex/latex3/xparse/xparse.sty)

               is available.

! Undefined control sequence.

If I comment out \usepackage{xfrac}, my document compiles without any 
errors.
