[Tex/LaTex] Missing ‘biblatex’ package

biberbiblatex

I'm attempting to create a bibliography using biber, via Tex Live (installed on a Linux Mint 11 machine).

My source .bib file is: 

@article{simon06,
  author = {Simon, E. and Flaschker, N. and Schadewaldt, P. and Langenbeck, U. and Wendel, U.},
  title = {Variant maple syrup urine disease (MSUD)--the entire spectrum},
  year = 2006,
  journal = {Journal of inherited metabolic disease},
  volume = 29,
  number = 6,
  pages = {716--24},
  pmid = 17063375,
  doi = {10.1007/s10545-006-0276-1},
  keywords = {}
}

My pmid.tex file is: 

\documentclass[]{article}

\usepackage[autostyle]{csquotes}

\usepackage[
    backend=biber,
    style=authoryear-icomp,
    sortlocale=de_DE,
    natbib=true,
    url=false, 
    doi=true,
    eprint=false
]{biblatex}
\addbibresource{pmid.bib}

\usepackage[]{hyperref}
\hypersetup{
    colorlinks=true,
}

%% ##############################
\begin{document}
    Lorem ipsum dolor sit amet~\citep{simon06}.
    At vero eos et accusam et justo duo dolores et ea rebum~\citet{simon06}.
    \printbibliography 
\end{document}

My sequence is:

pdflatex, biber, pdflatex

After running biber pmid, the resulting pmid.bbl file contains an error:

\begingroup
\makeatletter
\@ifundefined{ver@biblatex.sty}
  {\@latex@error
     {Missing 'biblatex' package}
     {The bibliography requires the 'biblatex' package.}
      \aftergroup\endinput}
  {}
\endgroup

biblatex is apparently not installed. I tried issuing tlmgr install biblatex, received no errors, but am continuing to get the 'missing biblatex' error.

Any help and/or guidance appreciated.

The construction 

\@ifundefined{ver@biblatex.sty}
  {\@latex@error
     {Missing 'biblatex' package}
     {The bibliography requires the 'biblatex' package.}
      \aftergroup\endinput}
  {}

is a test with two branches, which checks if biblatex is loaded. If it is, then \ver@biblatex.sty is defined and nothing happens. If it is not defined, the .tex file which read the .bbl file did not load biblatex. In that case an error is raised. Thus this is a safety precaution, not an error.
