Apple just gave me a supplemental Catalina update, and now sagelib is
building. If this works, I'll attribute it to some Apple problem.

I am trying to build on OSX Catalina, and everything seems to go well until
it builds sagelib, and I get a libpng not found.
Everything built nicely a few weeks ago. I am tempted to blame the upgrade
to catalina, but I also upgraded hombrew and XCode.
Any ideas?

The issue is that you redefined x after defining K. I wrote more on the
ticket.

Ignore my post. It went to the wrong email list. Sorry.

One way to do

Yes. I can confirm it works

I'm far from an expert on installing but it seems to me that you
tried to install an app compiled for 10.11.6 on a 10.14.5 computer.
Is this correct?
In case that is
Type
./sage
at the prompt. This starts sage.

I'm not sure why it isn't evaluating symbolic numbers like pi, but here's a
work-around:
sage: f = piecewise([((-pi-*1*, -pi/*2*),

Did you mean to type "sage -optional" instead?

In a browser you should see an interactive version. The code for that is
right in the source for the page. It's javascript relying on the threejs
