Hi @matthewfeickert @simonmichal ! So, we encountered a strange situation, __ONLY__ on M1 macs: ``` /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ -bundle -undefined dynamic_lookup -Wl,-rpath,/Users/phristov/opt/miniconda3/lib -L/Users/phristov/opt/miniconda3/lib -Wl,-rpath,/Users/phristov/opt/miniconda3/lib -L/Users/phristov/opt/miniconda3/lib -Wl,-rpath,$ORIGIN/../../.. -std=c++17 build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/PyXRootDCopyProcess.o build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/PyXRootDCopyProgressHandler.o build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/PyXRootDFile.o build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/PyXRootDFileSystem.o build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/PyXRootDModule.o build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/PyXRootDURL.o build/temp.macosx-11.0-arm64-cpython-39/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/bindings/python/src/Utils.o -L/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/build/src -L/Users/phristov/alisw/sw/BUILD/15c75174a0a1efe679d9440664506fcfe915f5bc/XRootD/build/src/XrdCl -lXrdCl -lXrdUtils -ldl -o build/lib.macosx-11.0-arm64-cpython-39/pyxrootd/client.cpython-39-darwin.so ld: library not found for -ldl ``` again, only with latest setuptools not with 60.8.2... while the `setuptools==60.8.2` works and seem to be our "solution" i'm unwilling to let this unsolved.. any idea about this strange thing?
