Hi @FFY00 , unfortunately it is still failing :(

Suggested change

	has_runtime_library=bool(hasattr(sys, 'dllhandle') orsysconfig.get_config_var('LD_LIBRARY'))
	has_runtime_library=bool(hasattr(sys, 'dllhandle') orsysconfig.get_config_var('LDLIBRARY'))

At least that's the variable I see here — and I can confirm that with this change, 3.14.0a4's test suite passes now for me.

It's no longer needed to skip the test, I updated the test instead: #129137
