我尝试petsc在 OSX 10.10.1 上使用 homebrew 安装：
$brew install petsc
安装一个依赖项时出现一个错误：
==> Installing petsc dependency: hypre
==> Using Homebrew-provided fortran compiler.
This may be changed by setting the FC environment variable.
==> Downloading http://ftp.mcs.anl.gov/pub/petsc/externalpackages/hypre-2.9.0b.tar.gz
Already downloaded: /Library/Caches/Homebrew/hypre-2.9.0b.tar.gz
Error: SHA1 mismatch

所以我尝试hypre用自制软件安装
$brew install hypre
我没有收到任何错误 ==> 摘要 /usr/local/Cellar/hypre/2.9.0b_1: 48 files, 4.5M
最后，我修改了petsc公式并注释掉了这一行
depends_on "hypre" => ["with-mpi", :recommended]
现在我可以安装petsc但它不起作用
