Got it, thanks! Again there's a lot of output, but the most important
bit seems to be here (with some context):

;; Here Guile is finishing loading its compiler
open("/Users/noah/Desktop/guile/guile/module/language/assembly/spec.go\0",
0x0, 0x0)                = 54 0
fstat64(0x36, 0x7FFF5FBFEC00, 0x7FFF70825630)            = 0 0
mmap(0x0, 0x3D2, 0x1, 0x1, 0x36, 0x100000001)            = 0xFE0000 0
stat64("/Users/noah/Desktop/guile/guile/module/language/assembly/decompile-bytecode.scm\0",
0x7FFF5FBFEA30, 0x10070A11B)             = 0 0
mmap(0x0, 0x19F, 0x1, 0x1, 0x1C, 0x1FFFFFFFF)            = 0x1F11000 0

;; At this point it's running the script
socket(0x2, 0x1, 0x0)            = 73 0                    ; make a socket -
INET family, SOCK_STREAM, internet protocol; we got one with
descriptor 73
fcntl(0x49, 0x3, 0x0)            = 2 0                      ; get flags for
file descriptor 49. result 2 probably means it is read and writable.
lseek(0x49, 0x0, 0x1)            = -1 Err#29             ; errno 29 is "illegal 
seek"
setsockopt(0x49, 0xFFFF, 0x4)            = 0 0      ; setsockopt on descriptor 
49
bind(0x49, 0x100709EE0, 0x10)            = -1 Err#49  ; bind descriptor 49.
errno 49 is "protocol driver not attached"

;; And now there's already been an error, and we'll backtrace it.
write(0x2, "Backtrace:\n\0", 0xB)                = 11 0
...

It seems to me that the strangest issue is that socket() return file
descriptor 73, but the script then did system calls on file descriptor
49. Does anyone know a reason that would happen?
