Installing 32-bit iSeriesAccess for linux on 64-bit machine.

I’m attempting to install the 32-bit version of iSeriesAccess for linux on a 64-bit Ubuntu 12.04 box. We were having some issues with the 64bit version and have confirmed everything works on the 32bit version with a 32bit box. I have gone through the installer the same way that I did on a 32bit machine however I’m getting the following error message when trying to connect with isql:

$ isql -v GBAS400
[01000][unixODBC][Driver Manager]Can't open lib '/opt/ibm/iSeriesAccess/lib/libcwbodbc.so' : file not found

the file /opt/ibm/iSeriesAccess/lib/libcwbodbc.so does exist.
