error while installing molden

[Marie Noella Brut]

I am trying to install molden, but after a few minutes, I get the following message:

--->  Verifying checksum(s) for molden
Error: Checksum (md5) mismatch for molden4.8.tar.gz
Error: Checksum (sha1) mismatch for molden4.8.tar.gz
Error: Target org.macports.checksum returned: Unable to verify file checksums
Error: Status 1 encountered during processing.

I have found a similar error in your archives and tried :

  port sync
  port install molden

But I still have the same error.

What can I do?

Many thanks,

Marie
