Your mod seems to think it requires one of the addons. WTF?

Moreover it requires not existing version of addon, there is only 1.4.1e version as most recent.

I'll have a 1.4.2 version of the thaumcraft add-on out very soon. Hopefully today. Sorry for the inconvenience.

New Thaumcraft add-on 1.4.2 is now out
