Comment (by ryandesign@…):

 But the error in the incomplete log is:
 {{{
 :info:destroot install_name_tool: object:
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_sysutils_e2fsprogs/libcomerr/work/destroot/opt/local/lib/libcom_err.1.1.dylib
 malformed object (unknown load command 4)
 }}}

 This suggests to me that your `install_name_tool` command is too old for
 the version of OS X you're running. Update your `install_name_tool`
 command by reinstalling the Xcode command line tools.
