Irmen de Jong:

I'm using homebrew on OSX 10.11.6 El capitan. Tonight I used it to upgrade to pypy 5.6.0 but this is now causing dynamic linking symbol issues.
I think it is caused by the fact that they offer a compiled pypy version that was created using the version 8 compiler tools on OSX 10.12 Sierra and I'm running it on the previous OSX version. Some googling results in dozens of projects having dyld symbol issues related to this, for instance https://github.com/civetweb/civetweb/issues/349 
I was wondering if this is something that homebrew should fix? Or is it something that should be fixed in pypy itself?

The exact error I'm getting:
