You need to either: 1) Use gcc from rawhide or 2) Edit the spec file and remove the changes that were done to work with gcc string merging, prelinking #1 is recommended, unless this is for a production system, in which case it is not recommended to use 4.1.0 yet anyway. I've resolved this bug by making gcc >= 2.96-93 a buildprereq in the specfile.
