Python and D (PyD)

[Fat_Umpalumpa]

Omg this was working a few days ago just fine! Now I can't even 
start the histogram example! I haven't changed the code and I 
know this worked a week ago.

dub still builds the program, however now when running the 
program, I get an error

object.Exception at ../../../.dub/packages/pyd-0.9.9/pyd/infrastructure/pyd/extra.d(74): numpy is not available

and then many more errors as if I have a problem with python or 
numpy... Crap I was installing random things with pip and may 
have ruined something.

I'll post a few more errors but I think the problem is on line 
(74) of the extra.d script
