importing healpy gives this warning:

WARNING: version mismatch between CFITSIO header (v40200) and linked library (v40300).

Then:

How to fix it?

[mreineck]

I can't be sure, but this looks like you compiled healpy yourself and maybe had some old .o files left in your tree.

Can you please try an installation from a clean checkout and report the commands and their outputs if the problem persists?

[mreineck]

... or perhaps this is related to #867 ?

Duplicate of #867.
