Hi, I have hit the same problem as lush. I'm trying to install the DBD::DB2 perl module. I am using perl 5.8.2 32 bit and trying to build the perl module using DB2 V9.1 on AIX 5.3 64 bit. I have already installed perl DBI. I am installing as root and using the correct path to DB2 include. I noticed that lush fixed the problem by installing DB2 V9.5 client. What I would like to know is can perl 32 bit connect to a 64 bit DB2 database?
