PKRU-Safe Build Using Docker Image

[MJUCOM]

Hi!
I build the PKRU-Safe to test the benchmark from servo. However, An error occurred while building the docker image. I use the pre-built docker image in https://hub.docker.com/r/mgdickerson/pkru-safe. And I process the following commends.

1. git clone https://github.com/securesystemslab/pkru-safe-automation.git automation
2. cd automation
3. docker pull mgdickerson/pkru-safe
4. docker run -it mgdickerson/pkru-safe

[In Docker Environment]

1. cd mpk-test/dir
2. cd automation
3. ./servo-requirement.sh
4. ./build-servo.sh -t all ( This commend occur the error !!)

And the error message like below

Exception: Could not detect environment shell!
make: *** [makefile.cargo:186: maybe-configure] Error 1

So, I spend more time to solve this error.. But i can`t solve this error.
Is there any solution or way to build the PKRU-safe and test the servo using benchmark??

Thank you!
Have a nice day!
