    Hi,<br>
    <br>
    I have been using the install script with the regular gcc-4.2 as
    suggested:<br>
    <br>
    ------------------------------------------------------------------<br>
    [ 9:12:39] Obiwan:$ CC --version<br>
    i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666)
    (dot 3)<br>
    ------------------------------------------------------------------<br>
    <br>
    It is so frustrating... yt was working great on my laptop a couple
    of months ago and I did not use it until 2 days ago, mainly to check
    that I was ready for the workshop. May be this shows that one should
    not spend a single week without using yt! ;-)<br>
    <br>
    Thanks for your help guys, I appreciate.<br>
    JC<br>
    <br>

            Hi JC,<br>
            <br>
            Unfortunately I'm not really sure -- I no longer have a Mac
            to test<br>
            against, and this error looks like some deep compilation
            bug, likely<br>
            with matplotlib.  It might be something about your
            installation (did<br>
            you use the install script?  were you using a non-standard
            GCC? etc)<br>
            but I'm not really sure.<br>
            <br>
            Anyone else out there, with a Mac, who might be able to give
            JC a pointer?<br>
