Django project: install phase times out

We're currently evaluating Railway because we want to move away from AWS and have a more pleasant and less manual infrastructure experience. It's a Django project. We need some extra Linux packages so I created the following nixpacks.toml:

[phases.setup]
aptPkgs = ["gettext", "libgdal30", "libxml2", "libxslt1.1", "libxslt1-dev", "swig", "openssl", "libssl-dev", "build-essential", "python3-dev"]

[phases.install]
cmds = ["python -m venv --copies /opt/venv && . /opt/venv/bin/activate && pip install --global-option=build_ext --global-option='-I/usr/include/x86_64-linux-gnu' -r requirements.txt"]

A new deploy is triggered for every push to Github, but it always times out during the install phase:

...
#11 237.9 Collecting pandas==2.0.3
#11 237.9   Downloading pandas-2.0.3.tar.gz (5.3 MB)
#11 238.0      ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 5.3/5.3 MB 64.0 MB/s eta 0:00:00
#11 238.9   Installing build dependencies: started
#11 365.5   Installing build dependencies: still running...
#11 434.1   Installing build dependencies: still running...
#11 506.3   Installing build dependencies: still running...
 
Build timed out

What could I do to get to the bottom of this and fix it?

Thank you!
