dbi-link with Sybase

This may not be the best list for my question, but I'm sure someone there will he able to help me

There's a mailing list dedicated to DBI-Link, see
http://lists.pgfoundry.org/mailman/listinfo/dbi-link-general

I'm trying to use dbi-link under RHEL5.3. Using PostgreSQL and Perl rpms from distro, installed
Sybase ASE 1.5.5 developers edition and DBD::Sybase using cpan -i.

My test programs, using pubs2 example database, work fine. They connect as:

$dbh = DBI->connect("dbi:Sybase:server=RHEL53I386", "teste", "123testando");

So I have a working DBD::Sybase install. But then I try to initialize dbi-link using the statement:

SELECT make_accessor_functions(
'dbi:Sybase:server=RHEL53I386',
'teste',
'123testando',
'---
AutoCommit: 1
RaiseError: 1
',
NULL,
NULL,
NULL,
'pubs2'
);

I get the error (from postgresql logs)

OpenClient message: LAYER = (7) ORIGIN = (2) SEVERITY = (6) NUMBER = (6)
Message String: ct_con_alloc(): unable to get layer message string: unable to ge
t origin message string: error string not available

)
"

I already tried forcing my database to en_US.UTF-8 and sourced SYBASE.sh from postgres bash_profile
script. Before that, the error was aboit missing dynamic libs.

I know this looks more a sybase thing than a postgresql thing but maybe someone can understand the
sybase error message and help me. After all I hope someone out there does use dbi-link

Do you know what that Sybase error means?
If you know that, maybe you can figure out what's wrong...

Does the connection to Sybase depend on environment variables?
I have had a problem like this with Oracle and DBI-Link, environment
variables of the postmaster didn't make it into DBI-Link functions.
If that is your problem, you can use the fifth argument to make_accessor_methods to pass
(YAML encoded) environment settings.
