Comment (by programmingkidx):

 I did the change that you wanted. I added "PortGroup
 legacysupport 1.0" right below the "PortSystem" text. This did appear to
 eliminate the posix_memalign problem.

 The next problem I encountered were with literals that had really large
 values in the file ImfFastHuf.cpp. This was solved by adding "ULL" to the
 right side of the literals.

 The current problem I have are these errors:
 info:build Source/OpenEXR/IlmImf/ImfSystemSpecific.cpp: In constructor
 'Imf_2_2::CpuId::CpuId()':
 :info:build Source/OpenEXR/IlmImf/ImfSystemSpecific.cpp:50: error: can't
 find a register in class 'BREG' while reloading 'asm'
 :info:build Source/OpenEXR/IlmImf/ImfSystemSpecific.cpp:50: error: can't
 find a register in class 'BREG' while reloading 'asm'
 :info:build Source/OpenEXR/IlmImf/ImfSystemSpecific.cpp:50: error: 'asm'
 operand has impossible constraints
 :info:build Source/OpenEXR/IlmImf/ImfSystemSpecific.cpp:50: error: 'asm'
 operand has impossible constraints

 This is the code that causes the error:
 #if defined(IMF_HAVE_SSE2) &&  defined(__GNUC__)

     // Helper functions for gcc + SSE enabled
     void cpuid(int n, int &eax, int &ebx, int &ecx, int &edx)
     {
         __asm__ __volatile__ (
             "cpuid"
             : /* Output  */ "=a"(eax), "=b"(ebx), "=c"(ecx), "=d"(edx)
             : /* Input   */ "a"(n)
             : /* Clobber */);
     }

 My x86 assembly language is kind of rusty. Anyone have a clue how to fix
 this problem?
