Checksum failure on mysql-connector-java

I am trying to install the mysql-connector-java port, but am encountering a checksum failure:

>sudo port install mysql-connector-java
--->  Fetching mysql-connector-java
--->  Verifying checksum(s) for mysql-connector-java
Error: Checksum (md5) mismatch for mysql-connector-java-5.0.4.tar.gz
Error: Target org.macports.checksum returned: Unable to verify file checksums
Error: Status 1 encountered during processing.

Is there a fix or workaround?

thanks
