latex file compilation very very slow

Hello all,

I have installed latex on my MacBook Pro (under tiger) using i-Installer.
I have compiled this very simple tex file:

\documentclass[12pt]{article}
\usepackage[french]{babel}
\usepackage[applemac]{inputenc}
\author{nobody}
\title{Débuter}

\begin{document}
\maketitle
\section{Section One}
C'est super
\subsection{Nice}
gros delire

\section{Title2}
$$x^2+\cos \mathrm{x}$$
\end{document}



and it took 5min to obtain the pdf file (I try few time), which is
very very slow ... 😟
(time pdflatex file.tex
real 5m22.547s
user 1m10.612s
sys 1m3.317)



I make a very simple test:

when I pass in SuperUser mode (in root user) and I compile my tex
file again the compilation is very very fast less than 2secondes ...

(I created also another account without the root permission, and the
compilation of my tex file is also very very fast).

On comp.text.tex group someone suggested me to repair all the permissions
(I used for this the Disk Utility from /Applications/Utilities/),
but unfortunately the problem persists.

Does anyone have an idea?
