We hope to have R14B04 to build out-of-the-box
on Lion. Our plan is to have 'configure' set up
the Makefiles so that beam_emu.c is built with
gcc-4.2 and everything else with the default
compiler (usually llvm-gcc-4.2.).

Until then, the easiest way to build Erlang/OTP
seems to be:

CC=gcc-4.2 ./configure
make

We have not run all test suites on Lion yet,
but I have successfully built Erlang/OTP and
run the emulator and compiler test suites.

Our long-term plan is to find out exactly what
causes the problem compiling beam_emu.c
and submit a bug report to the llvm team.
