I wound up with more errors when I tested it with -ff2c than without it on some platform. I think it was 10.6/x86_64, but I don't recall that for a fact. I'll try it again for my available platforms. > Question: why the ugly > -Wl,-framework,Accelerate,-dylib_file,/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib:/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib > > while -Wl,-framework,Accelerate seems enough? It was like that when I took the package over :-) .
