SCO installation help

Hi all,

Hope someone might know the answer.

Trying to install 7.4.5 ('cause its what I have) from source on SCO OpenServer 5.0.7

The compile succeeds, all be it with warnings...

gmake install -- OK
create the data directories -- OK

/usr/local/pgsql/bin/initdb - D /usr/local/pgsql/data -- OK
/usr/local/pgsql/bin/postmaster -i -B 256 D /usr/local/pgsql/data & -- OK

/usr/local/pgsql/bin/createdb test produces
LOG: setsockopt(TCP_NODELAY) failed: Protocol not available
createdb: could not connect ..........

Thanks in advance
Allan
