Hi Nathan and Matthew<br><br>I was able to solve the difficulties with the installation of Yt+Enzo by reinstalling everything in a /home/usr/local directory instead of the /usr/local with root privileges. As I mentioned, in the root partition gave me errors such as not been able to get a login screen etc, (even problems with my wireless connection!!); so I decided to put everything in my HOME directory. <br>
<br>More over, it is quite convenient here if new problems are added; as one David Collins helped us (several students and me) at the National Observatory of Mexico.<br><br>Although not the right forum here, I just want to let the Yt and Enzo community that a postdoctoral position in astrophysics is open at the National University of Mexico ...here is the link: <b><font color="#000099"><a href="http://www.astroscu.unam.mx/IA/images/PostdoctoralpositionAstrophysics.pdf" target="_blank">http://www.astroscu.unam.mx/IA/images/PostdoctoralpositionAstrophysics.pdf</a></font></b><br>
<br>just in case some one is interested.....<br><br>well, thanks for all your help ..<br><br>hector<br><br><br><br><br><div class="gmail_quote">On Mon, Jul 23, 2012 at 6:56 PM, Matthew Turk <span dir="ltr"><<a href="mailto:matthewturk@gmail.com" target="_blank">matthewturk@gmail.com</a>></span> wrote:<br>

</div>I think that sounds good -- note also that the install script comes<br>
with an "activate" script which will set these variables for you, and<br>
that way you can enter/exit the yt environment at will.<br>
<br>
Let us know if this doesn't work, and good luck!<br>
