I was not able to get the dependencies in this branch to work correctly with composer 2.2.5. Is there a step missing from the instructions? Here is the build dependency issue I am seeing:

• [[ -z fail ]]
• python3 -m pip check
  web3 6.0.0b3 has requirement jsonschema<5,>=4.0.0, but you have jsonschema 3.2.0.
  solana 0.25.0 has requirement httpx<0.24.0,>=0.23.0, but you have httpx 0.22.0.
  eth-utils 2.0.0 has requirement eth-hash<0.4.0,>=0.3.1, but you have eth-hash 0.5.0.
  The command '/bin/sh -c bash installer.sh $COMPOSER_PYTHON_VERSION fail' returned a non-zero code: 1
