Problem compiling PostgreSQL 8.1.4 on AIX.

Hello,

I am trying to set up pgsql on AIX 5.3L (2/2006)
I am using gcc 3.3 (the version supplied by IBM  (Linux application toolkit for AIX))
running make produced the following output

rm -rf ./testtablespace
mkdir ./testtablespace
/bin/sh ./pg_regress --temp-install --top-builddir=../../.. --temp-port=55432 --schedule=./parallel_schedule --multibyte=SQL_ASCII --load-language=plpgsql
============== removing existing temp installation    ==============
============== creating temporary installation        ==============
============== initializing database system           ==============

pg_regress: initdb failed
Examine ./log/initdb.log for the reason.

gmake[2]: *** [check] Error 2
gmake[2]: Leaving directory `/installs/PostgreSQL/postgresql-8.1.4/src/test/regress'
gmake[1]: *** [check] Error 2
gmake[1]: Leaving directory `/installs/PostgreSQL/postgresql-8.1.4/src/test'
gmake: *** [check] Error 2
make: 1254-004 The error code from the last command is 2.


Stop.

and I find the following in the logs.

I am using user pgsql which was created specifically for postgre who owns the installation directory.
the directories are chmoded 777 just to make sure no permission are causing problems.

any clues?
