no native spinlock support on os x 10.4.7

hello,

as requested:

../../../../src/include/storage/s_lock.h:543:2: error: #error
PostgreSQL does not have native spinlock support on this platform. To
continue the compilation, rerun configure using --disable-spinlocks.
However, performance will be poor. Please report this to pgsql-
bugs@postgresql.org.

This is compiling using darwinports' "port install postgresql" on mac
os x 10.4.7.  PostgreSQL version ..

--->  Attempting to fetch postgresql-7.4.12.tar.bz2 from ftp://
ftp2.ch.postgresql.org/mirror/postgresql/source/v7.4.12

cheers,

Nick!
