DBI is a module that relies on XS, meaning the bulk of it is written in C, the Perl part is mostly only a connection layer between Perl and the module. As a consequence, "placing it in the right place" can't work: the module must be built first, which involves a C compiler. You can use a module like CPAN to (optionally) download and install a module, or you can download it by hand, extract the .tar.gz file, and at the command prompt, cd to the main directory that got extracted, and type the following commands, one at a time: 
perl Makefile.PL
make
make test
make install

[download]
Do not proceed to the next command if the output of the last command doesn't look right. For example, do not type "make install" if "make test" complains.

Why am I even typing that here? The DBI docs even mention this, at the very top, under "quick start"

It is possible to "just place the files at the appropriate place" if you do have prebuilt binary files for your platform. For example, that's what Activestate provides for this kind of modules for Windows (all versions), for example: the XS parts come built as DLL files.
