Can't start Pgsql 7.1 on FreeBSD 4.2

 Postmaster spits out this :
IpcMemoryCreate: shmget(key=5432001, size=1236992, 03600) failed: Cannot
allocate memory
 When I try to start it. I compiled and installed from the ports
collection.

 I compiled these into my kernel :
options         SYSVSHM                 #SYSV-style shared memory
options         SYSVMSG                 #SYSV-style message queues
options         SYSVSEM                 #SYSV-style semaphores

 Any ideas?
