Oracle Generic DB Link not working - database

Question

I'm trying to use oracle's hsodbc generic database link driver to access a postgresql database from my oracle 10gr2 database server. I think I have everything configured but I'm receiving this error from the sqlplus promt after trying a remote query.
SQL> select * from temp_user#intranet;
select * from temp_user#intranet
*
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from INTRANET
If I use "isql" from the linux command line (in other words test just the odbc connection) the query works.
I enter in "isql intranet" (intranet is the name of the odbc connection)
I get the prompt I type select * from temp_user and I receive back my 157 records on screen.
So I know the odbc configuration is setup correctly. Here is what I do for oracle.
%oracle_home/hs/admin/inithsodbc.ora
HS_FDS_CONNECT_INFO = intranet
HS_FDS_TRACE_LEVEL = OFF
HS_FDS_SHAREABLE_NAME = /usr/bin/ODBCConfig
%oracle_home/network/admin/tnsnames.ora
INTRANET =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.5.1)(PORT = 5432))
)
(CONNECT_DATA =
(SID = INTRANET)
)
(HS = OK)
%oracle_home/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = INTRANET)
(PROGRAM = hsodbc)
(SID_NAME = INTRANET)
(ORACLE_HOME = /home/oracle/app/OraHomeTEST)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracledb.andersen-const.com)(PORT = 5432))
)
)
I have restarted the listener. It's status is as follows.
Services Summary...
Service "INTRANET" has 1 instance(s).
Instance "INTRANET", status UNKNOWN, has 1 handler(s) for this service...
I then go into sqlplus from the database server command line and do the following.
drop database link intranet;
create database link intranet connect to auser identified by apassword using 'intranet';
This is successful.
However when I run
select * from temp_user#intranet
I receive the error
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from INTRANET
I've spend atleast a good day going back over the configures and trying things and I always get this error.
Anybody have any good ideas,

What does "tnsping intranet" report?
Are you sure your hsodbc prorgram is in the Oracle_home/bin directory of the your gateway installation? Also, is your LD_LIBRARY_PATH set properly?
I believe your LD_LIBRARY_PATH should be $ORACLE_HOME/lib. Sorry, not sure since I don't do much with *Nix these days.
