"sudo port install gimp" hangs forever on "Building sane-backends"

[dylanarena@…]

I have a brand-new MacBook Pro running 10.7.2. I wanted to install GIMP, so I installed MacPorts from the AppStore and then called "sudo port install gimp" from Terminal. I saw a huge list of dependencies, which MacPorts diligently chipped away at for hours. But it seemed to have hung up at the following point in the process:

---> Fetching archive for sane-backends ---> Attempting to fetch sane-backends-1.0.22_1.darwin_11.x86_64.tbz2 from ​http://packages.macports.org/sane-backends ---> Fetching sane-backends ---> Attempting to fetch sane-backends-1.0.22.tar.gz from ​http://distfiles.macports.org/sane-backends ---> Verifying checksum(s) for sane-backends ---> Extracting sane-backends ---> Applying patches to sane-backends ---> Configuring sane-backends ---> Building sane-backends

It had been a few hours, so I hit control-C and then called "sudo port install gimp" again. Happily, this time the list of dependencies was very short:

---> Dependencies to be installed: xsane sane-backends

So I left the computer to run overnight. But when I returned to my computer this morning I saw that it had been hanging at the following line for at least ten hours:

---> Computing dependencies for gimp ---> Dependencies to be installed: xsane sane-backends ---> Building sane-backends

Can anyone help me diagnose the problem?

Thanks very much for your time, Dylan
