[yt-users] installing yt on mac osx 10.6

Hi Matteo,

yt is installed into a fully local directory, without touching
anything outside of it.  So -- worst case scenario is that you delete
that directory, undo your changes to your environment variables, and
it goes back to normal.

There are three variables it tells you to change in the
install_script.sh.  PATH, LD_LIBRARY_PATH, and PYTHONPATH.  It also
tells you to set YT_DEST.  Here's how it looks in my .bashrc -- if you
are using csh, yours would look differently.

export YT_DEST=/home/mturk/yt-x86_64
export PATH=$YT_DEST/bin:$PATH
export LD_LIBRARY_PATH=$YT_DEST/lib:$LD_LIBRARY_PATH
export PYTHONPATH=$YT_DEST/lib/python2.7/site-packages:$PYTHONPATH

(These usually go at the bottom.)  Note that in the definition of PATH
I also include the old value of PATH -- this is how programs like
gnuplot and so on can be found.  But I include the YT_DEST path first,
so that it gets searched before the other.

If you use csh, this will look differently, but I don't know csh so I
can't speak to how.

Now, another important note is that if you try to re-set these in an
existing shell, it won't bring back the original value of PATH -- if
you mistakenly do something like "export PATH=/something" then the old
version is gone, and you'll have to log out / log back in to get it
back from the systemwide profile.

Anyway, if you continue to have issues, it might be most productive if
you show us what PATH and LD_LIBRARY_PATH are set to in the shell
"echo $LD_LIBRARY_PATH" and "echo $PATH") and how you set them in your
~/.bashrc or ~/.cshrc.
