 Hi,

 running "sudo port install llvm-gcc4" results in the following error
 (excerpt from the log file, which is attached):

 {{{
 :info:build shell command " cd
 "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_release_ports_lang_llvm-gcc42/llvm-gcc42/work/build" && /usr/bin/make
 -j2 -w bootstrap BOOT_CFLAGS="-O2 -g -D_FORTIFY_SOURCE=0"
 STAGE1_CFLAGS="-O2 -fkeep-inline-functions -D_FORTIFY_SOURCE=0" " returned
 error 2
 }}}

 When running the second part of that shell command (make) by hand, the
 following error appears (full output attached):

 My system: MacOS 10.7.2, XCode 4.2, MacPorts 2.0.3

 Any help appreciated (and as always I hope that the bug is not me...)
 Regards,
 planck
