I ran it in a guile REPL (as root) and I got the first two outputs, but an error on (execl ...). It's an unhelpful message:
ERROR: In procedure execl:
ERROR: In procedure execl: Permission denied
The backtrace just shows me the line that failed.
When I save it in a file and run that with guile as root I get this error after the first two output lines:
Backtrace:
In ice-9/boot-9.scm:
157: 7 Exception thrown while printing backtrace:
ERROR: In procedure private-lookup: Module named (system vm frame) does not exist
ERROR: In procedure execl:
ERROR: In procedure execl: Permission denied
That's all.
