Help with imports

Hi there,

I was wondering if someone could offer some advice on where I'm going wrong with 
the following?

I'm defining a module:

```
amccartn@mc ~/dotfiles  (debug/home-services *)
> rg "define-module" admccartney/home-services/shell.scm
3:(define-module (admccartney home-services shell)
```

And then failing to import it elsewhere, despite having added the directory 
to the guile load path.

```
amccartn@mc ~/dotfiles  (debug/home-services *)
> tree -a ~/dotfiles/admccartney/home-services/
/home/amccartn/dotfiles/admccartney/home-services/
├── desktop.scm
└── shell.scm

1 directory, 2 files
amccartn@mc ~/dotfiles  (debug/home-services *)
> GUILE_LOAD_PATH=$GUILE_LOAD_PATH:$HOME/dotfiles/ guile

scheme@(guile-user)> ,import(admccartn home-services shell)
While executing meta-command:
no code for module (admccartn home-services shell)
```

Any help much appreciated!

regards,
Adam
