Build error due to runaway repeated _placehold string in history file

[oulenz]

I tried to build conda-opencv3 on ubuntu as described in the readme, but received the following error:

Can't build [...]/conda-opencv3/conda due to environment creation error:
IO error: Couldn't read or write to file. '[...]/anaconda3/conda-bld/opencv3_1489753787890/_b_env_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_pla/conda-meta/history'.
Can't write the history file [Errno 36] File name too long: [...]

(I was trying to build manually because I hoped this might get me OpenCV 3.2 for Python 3.6, although it looked like it was going to build 3.1, which has a critical bug. Any estimate as to when 3.2 will be available for 3.6?)

No estimate I'm afraid, I have PR open, but as always buildng OpenCV is incredibly time consuming.

Do you know how to fix it ?
