I'm writing a perl program that takes as input some tiff files, and outputs the total number of pages in all the files. The Imager module seems exactly like what I need. However, I'm having some problems.

1. How do I install tiff support for Imager?
2. Do I have to reinstall Imager afterwards? If so, how?

The documentation on the Imager CPAN site simply says, "If you have the necessary knowledge, install the image format libraries you want Imager image file support for, and Imager itself, otherwise arrange to have it done." This statement is not helpful.

In searching this site, I see that other people have asked similar questions, such as here

and here

but the posted solutions link to a readme file that no longer exist.
