Building elephant no longer working

[stinebuu]

A master student in our group had problems installing Elephant with Builder, adding the following to forms/elephant/<versjon>/default solved the problem

source_get() {
        log_status ">>> no source fetching necessary."
}

This should be fixed in master as well.

(She got the following error message before adding the changes: Builder/build_functions.sh: line 148: URL: Unbound variable)

This is probably caused by the URL line not being present, which is not (and should not be) used for Python packages. A fix as you did is reasonable for the moment and I'd probably still accept such PR, but we should have a look at the install mechanisms in general to make this unnecessary.
