Hi, I have sage-5.8-linux-64bit-red_hat_enterprise_linux_server_release_5.9_tikanga-x86_64-Linux installed on CentOS release 5.9 (Final). I installed via the binary. Is there any way to update the scipy installation to 0.12? I tried downloading the scipy-0.11 spkg and replacing the v11 source with the v12 source, and then doing sage -i <path to="" package=""> but it didn't work. Any suggestions? I really need to the new Welch functionality in scipy.signals
Thanks
