The fact that the blas package is seemingly listed twice implies that
you probably have both the i386 and x86_64 versions of the package
installed. To see the architecture of the installed packages, try
using the following query:

sudo rpm -q --queryformat="%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n" blas

Removing the package that does not correspond to your machine's
architecture should be harmless.
