postmaster failure with 2-23 snapshot

uname -a
SunOS vlad 5.7 Generic_106541-01 sun4u sparc SUNW,Ultra-5_10
gcc -v
Reading specs from
/opt/gnu/lib/gcc-lib/sparc-sun-solaris2.7/egcs-2.91.60/specs
gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release)

I just compiled the snapshot using this command to configure pgsql:

configure --prefix=/opt/pgsql \
--with-template=solaris_sparc_gcc \
--with-tcl \
--with-perl \
--with-tclconfig=/opt/tcl/lib \
--with-includes=/opt/tcl/include

All compiles fine, but when I try to run the postmaster I get the
following:

vlad: postmaster -i
IpcMemoryCreate: shmget failed (Invalid argument) key=5432001,
size=1137426, permission=600
FATAL 1: ShmemCreate: cannot create region

Thought it might help with the development.
Thanks.
