SuiteSparse checksum error

I'm trying to install octave and I get the following error: Verifying checksum(s) for SuiteSparse Error: Target com.apple.checksum returned: Could not open file: /opt/ local/var/db/dports/distfiles/SuiteSparse/SuiteSparse.tar.gz Error: The following dependencies failed to build: SuiteSparse dejagnu fftw-3 gcc42 gmp mpfr odcctools gnuplot gd2 pdflib readline hdf5 teTeX gawk gsed texi2html texinfo Error: Status 1 encountered during processing. I have tried removing the retrieved file and run again with the same results. I see that there are some patches posted for SuiteSparse today so, hopefully, this is just a transient problem? Thanks, Richard
