help using guix size command w/ local file definition

[chris]

How does one use `guix size` with a local file package definition?

I have copied the `vifm` package definition here to a local file https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/vim.scm?id=master#n916

Using `guix size --load-path` as described here fails https://guix.gnu.org/manual/en/html_node/Invoking-guix-size.html
```
$ guix size --load-path=$HOME/software/vifm-local/ vifm-local
guix size: error: no available substitute information for '/gnu/store/vx189rcgy4b8lw1acw14cki9lm4jz9jn-vifm-local-0.13'
$ guix size --substitute-urls="" --load-path=$HOME/software/vifm-local/ vifm-local
guix size: error: no available substitute information for '/gnu/store/vx189rcgy4b8lw1acw14cki9lm4jz9jn-vifm-local-0.13'
```

Another question, as guix's vifm input list includes `libx11`, shouldn't x11 appear in the size listing?
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/vim.scm?id=master#n916
```
$ guix size vifm

The package needs to be built first:

    /tmp/xxx $ guix size -L . vifm-local
    guix size: error: no available substitute information for '/gnu/store/rhvkgakmmf11lpz5jhpciyzramwd69vf-vifm-local-0.13'

The error message might be a bit misleading, especially with the empty
substitute urls.

The libx11 is present in the inputs, but since vifm defaults to dynamic loading
of it using dlopen, the store path is not present in the output binary and
therefore libx11 is not detected as dependency (I assume).

When you add "--with-dyn-X11=no" to #:configure-flags, the size output changes
to:

Which seems to be what you expected.  I know nothing about this packages, but my
guess would be this is just a packaging error instead of intentional
optimization (~6MiB do not really matter IMO).

Hope this helps,
Tomas
