Digging more.
The error is in dragonegg-2.8/llvm-backend.cpp

The version checks is done against the exact version of gcc:
----
  // Check that the running gcc has exactly the same version as the gcc
we were
  // built against.  This strict check seems wise when developing
against a fast
  // moving gcc tree.  TODO: Use a milder check if doing a "release
build".
  return plugin_default_version_check (gcc_version, plugin_version);

----

To run, dragonegg except the exact same version it has been built
with... (what a pain).

A workaround is to do:
dragonegg_disable_version_check=1 llvm-gcc -o foo foo.c 
which is working with your example.
