Hi Andrew.
Let's see if we can get to the bottom of this.
I'm really no expert here.

otools (as opposed to ldd) on arrayfuncs.so yields:

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
Err. Has any one tried building with clang yet? But I guess that's not
the problem ;)
I would have expected some atlas linker flags.
Do you by any chance know where
_ATL_drotg is defined? I have drotg from cblas and it is defined in
cblas.so. So I would guess some linker flag is missing.
Also, could you please run:
|from numpy.distutils.system_info import get_info; print
get_info('blas_opt', 0)|
This should tell us what numpy things are good compiler flags.
Andy
