Hi Guix,

I'm (still) trying to fix a build failure I (unsuccessfully) reported
here: <https://lists.gnu.org/archive/html/guix-devel/2022-02/msg00302.html>.

I've tried and produced a patch, but, somehow, I cannot make it work! :-(

```
+               (setenv "SHELL" (which "sh"))
+               (setenv "CONFIG_SHELL" (which "sh"))
```

I'm not sure those lines are required, but at this point I've just
copied/pasted code I found in an other package definition.


```
+               ;(invoke "./configure" (string-append "--prefix=" out)))))
+               (invoke "bash" "./configure" (string-append "--prefix=" out)))))
```

If I "just" invoke `./configure` I get an error code, but no error
message. I had to prepend `bash` to get the error message telling me
that `cc` and `gcc` were missing.


```
+  #:use-module (gnu packages commencement)
; […]
+    (native-inputs (list gcc-toolchain))
```

When I add `#:use-module (gnu packages commencement)` I get the following error
message I cannot decipher:

```
error: tcc: unbound variable
hint: Did you forget a `use-modules' form?

error: googletest: unbound variable
hint: Did you forget a `use-modules' form?

; […]

Throw to key `unbound-variable' with args `("resolve-interface" "no binding `~A' in module ~A" (python (gnu packages python)) #f)'.

Any advice welcome!
