@OkonSamuel Friendly reminder that a review would be nice.

I'm happy to drop it. But I'm trying to remember why we had it in the first place.
EDIT:
I remember now, For the linux builds we had an issue because the shared library used by Julia is different from that used by Conda. But since this PR runs it means that Julia dev team has updated the shared library used.
Rather than deleting it out totally, I recommend just comment the lines of code that aren't needed. Should in case we face a similar issue in the future.
