Zeoslib Portal

I have a problem connecting to mysql5 in debian using zeoslib.

my test program is very simple:

program zeotest;

uses ZConnection, ZDataset;

var
MyConnection: TZConnection;
MyQuery : TZQuery;
sSQL : widestring;


begin
sSQL := 'SHOW TABLES';

MyConnection := TZConnection.Create(nil);
MyQuery := TZQuery.Create(nil);
MyQuery.Connection := MyConnection;

MyConnection.Protocol := 'mysql';
MyConnection.HostName := 'localhost';
MyConnection.Database := 'mydatabase';
MyConnection.User := 'myuser';
MyConnection.Password := 'mypasswd';

MyQuery.SQL.Clear;
MyQuery.SQL.Add(sSQL);
MyQuery.Open;

while not(MyQuery.Eof) do
begin
Writeln(MyQuery.Fields[0].AsString);
MyQuery.Next;
end;
MyQuery.Free;
MyConnection.Free;
end.

the program raises an exception in module zeotest at 0809470D
and show the following error:
None of the dynamic libraries can be found: libmysqlclient.so

I have a symbolic link pointing to libmysqlclient.so.15.0.0.

This demo was working correctly on suse and using mysql4

Any ideas ??

Thanks in advance
