PostgreSQL 8.0.1 compile success Regression Fails

Hi ,

Compiled PostgreSQL 8.0.1 on FC3 Kernel 2.6.10

Configured with
./configure \--bindir=/usr/bin \--prefix=/postgres
\--libdir=/usr/lib/pgsql \--sysconfdir=/etc/sysconfig/pgsql
\--datadir=/postgres/data \--enable-syslog \--with-CXX \--without-tcl
\--with-pgport=5432 \--enable-thread-safety \--without-tk

the only problem is Regression test fails with following error

/bin/sh ./pg_regress --temp-install --top-builddir=../../..
--schedule=./parallel_schedule --multibyte=SQL_ASCII

Any suggestions. may I move ahead with installation or should I try
again from configure. I have already redone the whole process 10
times.
