biblatex-apa error [closed]

Question

This is my preamble

\documentclass[man,nobf,noapacite]{apa}
\usepackage[margin=1in]{geometry}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\bibliography{libros}
%\usepackage[utf8x]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{tgtermes}
\usepackage{float}

When I run bibtex on the aux file I get this:

This is BibTeX, Version 0.99c (TeX Live 2009/Debian)
The top-level auxiliary file: paper.aux
I couldn't open style file biblatex.bst
---line 2 of file paper.aux
 : \bibstyle{biblatex
 :                   }
I'm skipping whatever remains of this command
I found no style file---while reading file paper.aux
(There were 2 error messages)

I just did a full net-install of texlive 2011 in a Kubuntu Karmic machine, what could be the problem?

EDIT: The problem was an old version of bibtex that was installed in /usr/bin for some reason. I removed that and I can compile my code with no problems.

EDIT BY LOCKSTEP:

Here's a stripped-down compilable example that works for me.
