I changed the configure flags a bit (though I think I just removed ignored flags anyway.) Now the error is the lengthy error.log.

[saraedum]

I get that error --without-archnative and with these CXXFLAGS: -fvisibility-inlines-hidden -fmessage-length=0 -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -pipe -isystem $PREFIX/include -fdebug-prefix-map=$SRC_DIR=/usr/local/src/conda/fflas-ffpack-2.5.0 -fdebug-prefix-map=$PREFIX=/usr/local/src/conda-prefix

Tried again explicitly with openblas and still getting an error
