Oh, I'm jumping on this: can we have some pretty(ier) printing for the "object" too? Having all the attributes in line is kind of difficult to read, especially when there are several missing dependencies. Using pprint maybe?

>>> pprint.pprint(d)
{'dummy': True,
 'full_mod_name': None,
 'hidden': False,
 'name': 'imkl',
 'short_mod_name': None,
 'toolchain': {'name': 'dummy', 'version': 'dummy'},
 'version': '10.3.12.361',
 'versionsuffix': ''}

@kcgthb: we need a better approach to error messages all together, to make them more readable; see also #139, please include a comment with your suggestion there

I've been thinking on how to tackle this, and I think we need a dedicated error_reporting module which provides pretty printing functionality for errors. This module could provide functions like fatal_error(msg, err), report_missing_deps(deps), etc. Trying to pretty print things all over the place will be too messy, we need a more centralised approach.
