powerbuilder application running in Linux connecting to mysql

I have a powerbuilder program using MYSQL database running on a linux box. When 
the program is ran in the windows operating system, it uses a predefined DSN to 
connect to the database. The problem is that when i run the program in Linux, I 
cannot connect to the database even if i already installed MyODBC. I even 
tested the connection of the DSN I created in the Linux box and it is 
successful. However, when I ran the program in Linux, I am getting this message 
: " The allocation of the environment handle failed."

thank you for your help
