Hello Kyle,

I agree that putting /opt/local/bin in your PATH should be adequate, so this 
isn’t totally obvious. The executables athena, hephaestus, and artemis should 
all be in /opt/local/bin/. Are they?

What is the result if you execute the following?

$ port contents demeter


I’m the official maintainer of the Macports version of Demeter. Unfortunately, 
I’m not a regular user. In fact, it’s not installed on the everyday computer 
that I’ve had for four years (to give you an idea of what “not regular” means 
to me).

Worse, there’s a chronic problem that I have never worked out how to solve. The 
Demeter ports depends on many things. One is ifeffit, which is not really still 
supported, but Demeter can’t just magically start using Matt Newville’s 
replacement for ifeffit, known as Larch. It feels to me like Mac-Demeter is 
doomed to break permanently pretty soon, if it has not already.

[Bruce, Matt, have I stated that accurately? Please correct me if I’m wrong.]

Still, there exists a port for ifeffit and for demeter, and one should be able 
to install them. I’m trying it right now on a Mac that lacks them. It will take 
me a while, because I’m not a Perl user either, and there are dozens of 
dependencies to install first. Let’s see how it goes for me…

This install is taking a very long time. I’m going to send this note as-is and 
report later about whether I can make athena run, and where the executable is 
located. (But I’m sure it will be /opt/local/bin/ )

Could I suggest that, if you get it to work, and you use it regularly, and 
you’re an open-source supporter, would you think about helping as a second 
official maintainer of the Demeter port? Other users could benefit from me 
teaming up with an actual demeter user, to be sure!

Best wishes,

Hello All,
I’m a new postdoc at NREL, trying to install Demeter on my NREL Mac. I have 
previously only installed it on a Linux system. I followed the 
instructions<https://bruceravel.github.io/demeter/documents/SinglePage/macinstallation.html>
 for installing on a Mac, including the logout/login, and the installation 
appeared to be successful, with no errors. However, when I then try to run 
athena/artemis/hephaestus from the command line, I get a ‘command not found’ 
error.  Has anyone encountered this problem before? I thought I found a thread 
in the archives from 2014, but there was not response to the issue. I suspect 
it may be that the command location was not added to the $PATH, but am not sure 
where it is in order to add it.
Here’s the output from echo $PATH:
/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin
Any help would be appreciated!
Thanks,
Kyle
