Hi Maxim!
I got around to trying it your way, I think.
I have the manifest file `manifest.scm`:
~~~~
(specifications->manifest
'("erlang"
"emacs"
"emacs-org"
"emacs-erlang"
"emacs-ob-erlang"))
~~~~
~~~~
~~~~
~~~~
executing Erlang code block...
append-export-all: Symbol’s function definition is void: string-join
~~~~
~~~~
~~~~
