If you can, you may want to consider using perlbrew. You can install a specific version of perl, and you can force it to install a 32-bit version of perl. See this post for instructions on how to install a 32-bit perl using perlbrew. Although that node is specific to Mac OS X, I think it should also work on linux. After installation of your 32-bit perl using perlbrew, you can switch to that version of perl using the perlbrew command line application. Then, that particular perl installation should work with 32-bit libraries.
