I'm trying to construct dev-python/pdm-pep517::crocket-overlay which is required by net-misc/aria2p::crocket-overlay. Aria2p is a terminal frontend to aria2c download manager daemon. Gentoo linux is about to get its first proper download manager. This is the error. * Package: dev-python/pdm-pep517-0.8.4 * Repository: crocket-overlay * USE: abi_x86_64 amd64 elibc_glibc kernel_linux python_targets_python3_9 userland_GNU * FEATURES: network-sandbox preserve-libs sandbox userpriv usersandbox * python3_9: running distutils-r1_run_phase distutils-r1_python_compile python3.9 -m pyproject2setuppy build -j 8 Traceback (most recent call last): File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/lib/python3.9/runpy.py", line 87, in _run_code exec(code, run_globals) File "/usr/lib/python3.9/site-packages/pyproject2setuppy/__main__.py", line 55, in <module> main() File "/usr/lib/python3.9/site-packages/pyproject2setuppy/__main__.py", line 48, in main raise NotImplementedError( NotImplementedError: Build backend pdm.pep517.api unknown Reproducible: Always
