[gradsusr] Error while installing Grads on MacOS Big Sur

[Kanhu Charan Pattnayak]

Dear Grads User Forum,
Recently, I updated the OS MacOS Siera to MacOS Big Sur. I was trying
install Grads on it through Macport. It didn't give any error while
installation. But I am not able to open grads on my system. It is throwing
the following error.
GX Package Error: Could not find a record for the printing plug-in named
"Cairo"

  * The environment variable GAUDPT has not been set

  * Unable to open the default User Defined Plug-in Table:
/Users/kanhu/Downloads/grads-2.2.1/data/udpt

  Please read the documentation at
http://cola.gmu.edu/grads/gadoc/plugins.html


I am not sure about how to fix the error. As the error indicates I need to
have some plug in files *updt* and *Cairo*. I don't know how to get these
files. I would appreciate if someone could guide me to fix these issues.
I used the following commands to install grads on my PC.
