This is a special case of a more general, non-Python problem which you
will have to address if you want to build an industrial controller.

If your target has no C compiler[1], you have to set up a cross-compiling
environment.  I'd be surprised if the eBox doesn't come with
documentation covering this.

If there are special procedures and requirements for cross-compiling
Python (someone else indicated there are), I guess the Python
installation notes must cover this in a general way.

[1] Or even if it has one. It is much more convenient to build in your
    normal work environment where you have plenty of disk, CPU and RAM,
    a good text editor, version control, Perl ...
