I recently tried building python-cryptography with 3.4.5, like this: (arguments `(#:python ,python-3.4)) But, it fails like this: patch-shebang: ./setup.py: warning: no binary for interpreter `python' found in $PATH phase `patch-source-shebangs' succeeded after 0.2 seconds starting phase `patch-generated-file-shebangs' phase `patch-generated-file-shebangs' succeeded after 0.1 seconds starting phase `build' running "python setup.py" with command "build" and parameters () In execvp of python: No such file or directory phase `build' failed after 0.0 seconds I assume that python-wrapper needs to be adjusted somehow, but I'm not sure. Any advice?
