You would be much better off posting your question to dbi-users@perl.org (you don't need to subscribe in order to post) and you won't be automatically subscribed either. Very few people actully use or view this form for dbi or driver support. dbi-users is where you'll get the best support
Looks like you have compiled against 64bit binarys. DBI and DBD need to point at the 32 bit binarys.
find where the lib32 is on you system and point your LD_LIBRARY_PATH to that dir.
