[Chicken-users] error unbound variable w/ srfi-13 and/or module importing

[masukomi]

I've had a heck of a time getting things to compile statically with
modules. Now, I'm pretty sure I've discovered a related problem that's
either _in_ or triggered by srfi-13

here's my boiled down test harness (a simple hello world)

testing.scm
```
#!/usr/bin/env csi -script

(import hello)
(howdy "world")
```


hello.scm
```
(module hello

  (howdy)
  (import scheme)
  (import chicken.base)
  (import chicken.format)
  (import srfi-13) ; <------ this line is the problem

  (define (howdy who)
    (print (format "howdy ~A~%" who))))
```


compilation:
```
csc -unit hello -cJ hello.scm; csc -link hello -static testing.scm; ./testing
```

error
```
Error: unbound variable:

    <eval>      (##sys#load-library (##core#quote library))
    <eval>      (##sys#load-library (##core#quote expand))    <--

```

If i comment out the `srfi-13` import it runs without error. If I
leave it in, it does not.

Note that running the source file `./testing.scm` works perfectly.
it's ONLY the compiled version that gives the error. I've tried
uninstalling and reinstalling 'srfi-13`. I've also tried importing
`utf8-srfi-13` instead of `srfi-13`. I've tried this in different
files to make sure it wasn't some weird hidden character in one file.

I'm kind-of at a loss as to what's going on here. Any help would be appreciated.

Thanks in advance,
