"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

Please remember to use WikiFormatting for shell output, set the port field and Cc the maintainer.

Can you attach the logfile pointed to by port log sane-backends? Also, do you see extensive memory usage while the process runs and does everything get very slow?
