Comment (by mascguy):

 Sorry it took so long to get back to this.

 Based on some digging, it looks like the OpenCL dependency may be coming
 from hwloc (which openmpi-* ports depend on):

 {{{
 $ otool -L /opt/local/lib/libhwloc.dylib
 /opt/local/lib/libhwloc.dylib:
         /opt/local/lib/libhwloc.15.dylib (compatibility version 20.0.0,
 current version 20.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1252.250.1)
         /opt/local/lib/libxml2.2.dylib (compatibility version 12.0.0,
 current version 12.10.0)
         /System/Library/Frameworks/OpenCL.framework/Versions/A/OpenCL
 (compatibility version 1.0.0, current version 1.0.0)
 }}}

 Whether we can disable OpenCL usage for hwloc or not, without impacting
 our users, is another story. More digging to follow.
