Comment(by ryandesign@…):

 The relevant error shown several times in the log is:
 {{{
 dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib
   Referenced from: /opt/local/bin/grep
   Reason: Incompatible library version: grep requires version 8.0.0 or
 later, but libiconv.2.dylib provides version 7.0.0
 }}}
 The most common reason for this is that your libiconv port is built for
 the wrong architecture. And the most common reason for this is that you
 upgraded this machine to Snow Leopard from an earlier OS (or migrated data
 to this Snow Leopard machine from a Mac with an earlier OS), and that you
 had MacPorts installed on that previous OS/machine, and you have not since
 then uninstalled and reinstalled all ports. See the [wiki:Migration
 Migration] page in the wiki for how to do that.
