RE: installing ARTS

I've tried to install ARTS via MacPorts a couple of times now (on different machines), and I keep getting this error: ---> Verifying checksum(s) for arts Error: Checksum (md5) mismatch for arts-1.1.2.tar.bz2 Error: Target com.apple.checksum returned: Unable to verify file checksums Error: Status 1 encountered during processing. Is there any way around it, short of one of the maintainers or devs fixing the checksum for this package? (Note: I am running the current version of MacPorts, have run clean on it, and have done multiple syncs.) Thanks!
