Cross-talk between builds on mac builders

For some reason, on the mac builders, there is some cross-talk happening between different build directories.

Listing ~/.conda for the gitlab user, I see where that potentially comes from:

Contents of ~/.conda/envs.txt:

sh cat .conda/environments.txt
/Users/gitlab/builds/f6f95b82/0/bob/bob.conda/miniconda
/Users/gitlab/builds/f6f95b82/0/bob/bob.ip.annotator/miniconda/envs/bdt
/Users/gitlab/builds/f6f95b82/0/bob/bob.devtools/miniconda

Example broken build (notice the package is being built within bob.conda!): https://gitlab.idiap.ch/bob/bob.ip.annotator/-/jobs/156398
