otools (as opposed to ldd) on arrayfuncs.so yields:
(1) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 169.3.0)
(2)
/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate
(compatibility version 1.0.0, current version 4.0.0)
I'm hoping this isn't an issue with OSX Accelerate.
arrayfuncs.so was built as follows:
/usr/bin/clang -bundle -undefined dynamic_lookup -L/opt/local/lib
build/temp.macosx-10.8-x86_64-2.7/sklearn/utils/arrayfuncs.o
-Lbuild/temp.macosx-10.8-x86_64-2.7 -lcblas -lm -o sklearn/utils/arrayfuncs.so
-Wl,-framework -Wl,Accelerate
Thanks again!
