Is py25-numpy corrupted?

[David Rowe]

I am trying to install some ports (probably Gramps) that seem to require 
py25-numpy - this is not currently installed in my copy of MacPorts.
On trying to install p25-numpy, I get the following log:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
bash-3.2# port install py25-numpy
--->  Fetching py25-numpy
--->  Verifying checksum(s) for py25-numpy
Error: Checksum (md5) mismatch for numpy-1.0.4.tar.gz
Error: Checksum (sha1) mismatch for numpy-1.0.4.tar.gz
Error: Checksum (rmd160) mismatch for numpy-1.0.4.tar.gz
Error: Target org.macports.checksum returned: Unable to verify file 
checksums
Error: Status 1 encountered during processing.

This looks as if one of the files is corrupted on the MacPorts server or 
else the portfile is not consistent with the downloaded files.

Has anyone else experienced this before? Is there a workround?

Thanks for any help you can provide
