Yeah, I'm not fond of the way line-breaks work on here either - you need to put <br> in your text to get a line-break.

The simplest way to install under some specific directory is to supply a PREFIX parameter:

With Imager, since it has XS components, the files will actually be installed in a directory under that, for me it's /home/tony/lib/i386-linux-thread-multi/, so you'll need to set PERL5LIB to match.
