Please tell us more about the hardware setup. Is it an HPC cluster, and you 
trying to build Sage on an NFS-mounted (or fuse-mounted)
disk rather than on a local disk?
 
The locking errors like you show are typical for this setup; 
please build Sage on a local disk rather than on an NFS-mounted one
(this would be faster, too)
