--------------------+--------------------------------
 Yosemite 10.10.1, Xcode 6.1 (with command line tools installed as part of
 it)

 The error:

 --->  Building gcc49
 Error: org.macports.build for port gcc49 returned: command execution
 failed
 Please see the log file for port gcc49 for details:

 The log file is attached

 The first error in the log relating to this appears to be:

 :info:build
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc49/gcc49/work/gcc-4.9.2/libgcc/../gcc/tsystem.h:87:19:
 fatal error: stdio.h: No such file or directory

 I was able to install gcc48 with no trouble.
 This is a completely clean install.  All references to the previous
 (Mavericks) install of Macports were removed.
 Following the error message instructions, I did a "sudo port clean gcc49"
 and re-ran the install.  Same result.
