iTerm and Zsh

[Une Bévue]

Hey all,

i'd like to use iTerm with zsh

alltought my zsh setup works well with Terminal.app, iTerm.app  
complains about my PS1 definition and the way i've writen some aliases :

-sh: alias: -g: invalid option
alias: usage blahblah

with Terminal.app i don't have a .zshrc, all my zsh setup is under  
$ZDOTDIR

ZDOTDIR = HOME/Library/init/zsh

and even doing symlinks to all of my .z*  under ZDOTDIR don't work.

something strange to me is that it's sh reporting errors...

best,

Yvon
