Hi guix, I noticed that 'patch-shebang' in (guix build utils) does not work if the shebang is something like '#!/usr/bin/env -S python3 -u'. So it is not able to patch shebangs with multiple arguments https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#g_t_002dS_002f_002d_002dsplit_002dstring-usage-in-scripts
With the shebang above I get this error in the build phase: "patch-shebang: main.py: warning: no binary for interpreter `-S' found in $PATH". By looking at the function, this makes sense since in the let* bindings 'cmd' is bind to 'arg1' which is just '-S'. So the fix would not be too hard to implement. Cheers, Théo
