 Replying to [comment:4 brookemgilbert@…]:
 > I looked into that a while back and read [ticket:39868 this topic] about
 it. I think the problem is that my ISP automatically redirects me to a
 search page if I request a nonexistent address.

 The problem is that the DNS servers you are using return results for
 queries which should fail.
 The search page you mentioned is another symptom of this same problem.

 > I don't think that's under my control, but if it's important I could
 call them to see if they can turn it off...

 You should contact your ISP and tell them that this behavior of their DNS
 server is a violation of Internet standards. If they will not fix their
 DNS servers to comply with Internet standards, it's within your control to
 configure your router or computer to use different DNS servers that do
 comply with the standards. For example, I use Google DNS.

 Ok, that is the right checksum. So you do appear to have the right file.
 So the DNS problems don't seem to be contributing to this particular
 problem. So what is? We could try to run a version of the command MacPorts
 is trying to run to extract the file, and see if we get any additional
 errors that MacPorts didn't mention. I'd do this in a temporary directory
 that automatically cleans itself up after a few days, such as /tmp:

 {{{
 cd /tmp
 /usr/bin/bzip2 -dc
 '/opt/local/var/macports/distfiles/gmp/gmp-6.0.0a.tar.bz2' | /usr/bin/tar
 -xf -
 }}}

 If this is successful, it should print no output, and a directory
 "gmp-6.0.0" should have been created. If it's not successful, maybe it
 prints a warning or an error. I am wondering if your system's bzip2 and/or
 tar utilities may be broken.
