Note that it's not a crash; just a build failure. It looks identical to the one reported here:

https://trac.macports.org/ticket/50950

That user was on Yosemite and using the gcc5 variant. You're using the gcc48 variant. The latest stable version of gcc is now 6. Can you re-try and use the gcc6 variant this time? Or, if there is not a specific reason why you need openblas built with gcc, use the default variants.

Also, if you upgraded to El Capitan, did you upgrade Xcode and the command line developer tools too? Use the latest version of both, currently 7.3.1.
