[tex-live] TL2009 install-tl failing

[MORREALE Jean Roc]

Hi,

I'm trying to instal TL 2009 by following the steps of the pretest's 
page but I fail. Here is what I've done so far.

# rsync -r --delete --exclude=2008 --exclude=mactex* 
rsync://guiling.fr/texlive/ /home/jrm/texlive2009
# cd /home/jrm/texlive2009
# sh ./install-tl -repository /home/jrm/texlive2009 -no-gui -lang fr
./install-tl: line 24: my : commande introuvable (command not found)
./install-tl: line 25: Erreur de syntaxe près du symbole inattendu « ( » 
(syntax error near unexpected symbol)
./install-tl: line 25: `$svnrev =~ m/: ([0-9]+) /;'

I don't know which software is providing the 'my' command (googling my 
isn't helpful). Any hints on how I could get install-tl working ?
