APAcite on Mac OS X with texlive

While compiling a LaTeX document, a blank template of my PhD thesis to be exact, when I got the following error "! LaTeX Error: File `apacite.sty' not found." Again a quick search for Mac ports indicated that the texlive-bibtex-extra package was required. It was quickly installed using;

sudo port install texlive-bibtex-extra

Subsequent compile yielded more errors, this time it was "! Undefined control sequence. \abstract". This was solved using the texlive-latex-extra package, installed using;

sudo port install texlive-latex-extra


Then adding the following to define the abstract in the book documentclass;

% Define abstract in book documentclass
\pagestyle{empty}
\newenvironment{abstract}%
{
  \onehalfspacing%
  \null
  \vfill
  \chapter*{\centering Abstract}%
  \addcontentsline{toc}{chapter}{Abstract}
}%
{\vfill\null}

% Start the actual abstract
\begin{abstract}
\end{abstract}

More errors resulted "! Use of \@year@ doesn't match its definition." I had to add "\bibliographystyle{apacite}" to the bibligraphy page, and all was well once again.
