`bdt` assumes `mamba` to be in base environment

I have just installed bob.devtools to develop a local package. To not screw up my base environment, I have installed mamba and bob.devtools in a separate conda environment:

conda create -n bob-devel python=3.8 mamba -c conda-forge
conda activate bob-devel
mamba install bob.devtools -c https://www.idiap.ch/software/bob/conda/label/beta/ -c conda-forge

When I now want to build my-package, I get the following error message:

(bob-devel)$ bdt create -vv my-package
...

This seems that the script looks for mamba in the base environment, but actually it is only in my current environment:

(bob-devel)$ which mamba
.../miniconda/envs/bob-devel/bin/mamba

Is there a way to use mamba from my current environment?
