How to make contrib/sepgsql on Ubuntu Maverick ?

Hi,

My build script:
-------------------------------------------------
#!/bin/sh
set -v
set -e
cd /media/sda5/postgresql-9.1devel/build
export CFLAGS="-g3 -gdwarf-2"
../../tmp/postgresql-git/postgresql/configure
'--srcdir=../../tmp/postgresql-git/postgresql' '--enable-cassert' \
'--enable-nls' '--enable-integer-datetimes' '--with-perl' '--with-python'
'--with-tcl' '--with-krb5' '--with-openssl' \
'--enable-thread-safety' '--with-ldap' '--with-gssapi' '--with-pam'
'--with-libxml' '--with-libxslt' '--with-selinux' \
'--prefix=/media/sda5/postgresql-9.1devel/20110204' > configure-out1.log
2>&1
make world > make-out1.log 2>&1
make install-world > make-install-out1.log 2>&1
exit 0
--------------------------------------------------------

tail make-out1.log:
------------------------
make -C sepgsql all
