Errors making 4.11.0 virtual env

Hi, I’m trying to build Hue 4.11.0 from tarball after installing the dependencies. However, the makefile errors at the virtual environment:
[user@system hue-release-4.11.0]# PREFIX=/opt/hue make install
“PYTHON_VER is python3.9.”
“SYS_PYTHON is /usr/bin/python3.9.”
“ENV_PYTHON is /opt/hue/hue-release-4.11.0/build/env/bin/python3.9.”
“SYS_PIP is /usr/bin/pip3.9.”
“ENV_PIP is /opt/hue/hue-release-4.11.0/build/env/bin/python3.9 /opt/hue/hue-release-4.11.0/build/env/bin/pip.”
— Creating virtual environment at /opt/hue/hue-release-4.11.0/build/env
— Virtual environment /opt/hue/hue-release-4.11.0/build/env ready
touch: cannot touch ‘/opt/hue/hue-release-4.11.0/build/env/stamp’: No such file or directory
make: *** [Makefile:138: /opt/hue/hue-release-4.11.0/build/env/stamp] Error 1

The entire directory /opt/hue/hue-release-4.11.0/build doesn’t seem to get created. What mechanism is responsible for creating the virtual environment directories and how can this be resolved? I’ve tried manually creating the directory so the ‘stamp’ gets touched, but this results in errors being thrown in the resulting files.
