[yt-users] install/compile error

[Alexander Heger]

Dear yt team.

It turns out this is caused by a bug in python 3.5.0.  There is now a 
patch (for python 3.5.0)

http://bugs.python.org/issue25150

On 15/09/15 15:02, Alexander Heger wroteMaybe next yt release can be 
adjusted to circumvent running into this bug, but maybe also not necessary.

Best wishes,
Alexander
