There are many ways to install perl modules. The following are a few methods I use often -

Login Type	Package Type	Possible Action
SSH, telnet, Unix, no internet access from server	Source Package	scp or ftp source package (*.tar.gz) onto remote server, then unpack in a work directory - tar -zxvf pkg.tar.gz [download] Change into the package directory and make Makefile.PL make make install make test [download]
SSH, telnet, Windows, no internet access from server	Binary Package (ppm)	scp or ftp the ppm package onto remote server, set ppm repository to point to work directory on remote server, and ppm --install package. Be sure to read the ppm documentation on ActiveState website here
SSH, telnet, Windows, has internet on remote server	Binary Package (ppm)	Log onto the remote server and ppm --install package.
SSH, telnet, Unix or Windows, Remote server has no compiler	Source Package with XS components	Install package by hand - Compile the source package on local machine first (assume of the same architecture) 'Tar' up the compiled binaries ftp/scp onto the remote server Log onto the remote server and unpack the package make install on the remote server (or drop the perl .pm files under perl/site/lib, and XS binaries under perl/lib/auto/...)
