Thank you.

I don't think we need the Python2 variant. Otherwise, LGTM.

Thank you.

I couldn't build it because gperftools currently has a failing test.

IIUC correctly, these are the suggested build options in the README. It
may be worth adding a comment about it since this looks a bit
opinionated.

This does not belong to the set of suggested build options. Is there
a particular reason to activate it? If so, would it make sense to add
a comment about it?

I also see there is a "BUILD_SHARED_LIBS" flag, off by default. Would it
make sense to activate it?

> +    (license (list license:expat     ;; SymEngine.

In both comments, there should be a single semicolon and no full stop.

Could you send an updated patch?

That was part of the optimized build suggestions. I removed it, since
this feature is provided by gperftools and it's causing trouble.

The shared library is used by the Julia wrapper. I noticed that we have
a Julia build system, so I enabled this too.

The other suggestions were also applied.

I applied both patches. I had to fix indentation. You may want to find
out why it was off.

Thank you!
