you can do brew install libpng
which would install libpng 1.6.37 into /usr/local/ (I think, by looking at https://github.com/Homebrew/homebrew-core/blob/master/Formula/libpng.rb) you can also install a lot of other homebrew packages, such as gmp, etc to account for more packages on https://trac.sagemath.org/ticket/27330 I've tweaked/wrote some Homebrew formulas to get flint and arb brew install dimpase/science/flint brew install dimpase/science/arb from https://github.com/dimpase/homebrew-science (probably many more can be done this way too) On Wed, Nov 20, 2019 at 11:22 PM Paul Masson <paulmas...@comcast.net> wrote: > > I have Homebrew installed but have rarely used it so assumed it wasn't part > of the problem.
