New description:

 The attached Portfile.diff adds the changes required to build against the
 Apple clang 7.0 compiler and older. This include...

 1. Adding a clang-optimization.patch to use #pragma clang optimize
 off/#pragma clang optimize on to avoid optimization bugs in compiling two
 subroutines under Apple Clang 6.0 or later.
 2. Use of reinplace to avoid passing -module and -no-undefined under the
 clang compiler
 3. Removal of the clang compiler blacklist and the section preventing
 builds on El Capitan

 Tested on darwin15.
