Do you have the following defined in your kernel config file, so that you
have a valid shmget call?
#
# These three options provide support for System V Interface
# Definition-style interprocess communication, in the form of shared
# memory, semaphores, and message queues, respectively.
#
options SYSVSHM
options SYSVSEM
options SYSVMSG
BTW, where are the sources to this?
