macports erlang build disables smp by default

[Fred Dushin]

I thought I'd mention this to any macerlangers out there.  Discovered  
this testing some concurrency code, and saw the following in the  
erlang Portfile:

configure.args  --prefix=${destroot}${prefix}	\
		--enable-threads		\
                 --enable-kernel-poll            \
		--enable-hipe			\
		--disable-smp-support

There is an smp variant, though, which you can use to enable smp  
support.  I wonder if we should make this the default, no?  Are there  
some known bugs in the smp code?  (I know /my/ code runs 2wice as fast  
with it on... :)
