internal compiler error

     Type:  defect                       |     Status:  new
 Priority:  Normal                       |  Milestone:
Component:  ports                        |    Version:  2.2.1
 Keywords:  libgcc, mavericks, gfortran  |       Port:  libgcc +universal
-----------------------------------------+--------------------------------
 I'm trying to get MacPorts 2.2.1 to install gcc48 +universal on a 10.9.2
 machine, XCode 5.1, command line tools installed manually from
 commandline_tools_os_x_mavericks_for_xcode__march_2014.dmg

 I start with a completely clean installation of macports (i.e. rm -rf
 /opt/local, installing macports from the binary installer dmg), do a
 selfupdate, upgrade outdated, then "port install gcc48 +universal"

 I get an error while building libgcc referring me to
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc48/libgcc/main.log

 In there I see the apparent problem:
 {{{
