Postgresql 9.0.4 initdb bug on solaris 64 bit

Hi,

I'm trying to install Postgresql 9.0.4 on solaris but ran into problems
when trying to run the "initdb" command under the postgres Unix account.

[Server OS Version]
Oracle Solaris 10 9/10 s10s_u9wos_14a SPARC

[Downloaded source code from Postgresql and unzipped in the "/usr/postgres"
directory]

[Message I get when I run initdb]
$ initdb -D /usr/local/pgsql/data
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locales
COLLATE: en_US.ISO8859-15
CTYPE: en_US.ISO8859-1
MESSAGES: C
MONETARY: en_US.ISO8859-15
NUMERIC: en_US.ISO8859-15
TIME: en_US.ISO8859-15
The default database encoding has accordingly been set to LATIN1.
initdb: encoding mismatch
The encoding you selected (LATIN1) and the encoding that the
selected locale uses (LATIN9) do not match. This would lead to
misbehavior in various character string processing functions.
Rerun initdb and either do not specify an encoding explicitly,
or choose a matching combination.
