regina

[Enrique Artal]

I wanted to take a look to regina in sagemath, but I am not able to install it. I can install it outside sage with pip (version 7.3.1.1). With sage -pip install regina I get in both10.8 and develop:

So you must be on a non-manylinux platform?


./sage --pip install --no-binary regina regina
fails for me with

I'm not surprised that it doesn't build from source, as their build
system is very much outdated.
