From https://github.com/erlang/otp/pull/46#issuecomment-21719585

"Since b29ecbd (OTP-10418, R15B03) Erlang does not compile anymore with
old versions of GCC that do not have atomic ops builtins on platforms
where there is no native ethread implementation (e.g. ARM): (...)

Please note however that I will be merging this branch as well,
which will mean that you have to explicitly tell configure that
you intend to use the fallback atomic operations though
--disable-native-ethr-impls or --disable-smp-require-native-atomics."

Translated: On NetBSD-5.1 (with gcc-4.1.3) the erlang package
didn't compile because of

>  ../include/internal/gcc/ethr_membar.h:49:4: error:
>	#error "No __sync_val_compare_and_swap"

Adding the abovementioned option --disable-native-ethr-impls make the
Erlang runtime system use the original (now fallback) code. This should
maybe be an pkg option, but for now this has to do.
Explicitely enable XFT support unless GTK+ was compiled without X11 support
under Mac OS X. This fixes the text output under Mac OS X if GTK+ was
actually compiled with X11 support.
Note update of the "xchat" package to version 2.8.8nb21.
Missing documentation update for the new default behaviour of "FETCH_USING".
