for me, i download modules to my /tmp directory, so id download Sys-AlarmCall-1.2.tar.gz..then id do the following:

$ cd /tmp
$ tar -zxvf Sys-AlarmCall-1.2.tar.gz
[download]

this is where it would show the files being unzipped and a directory call Sys-AlarmCall-1.2 would be created

$ cd Sys-AlarmCall-1.2
[download]

now we're in the Sys-AlarmCall-1.2 directory which is where Makefile.PL is

$ perl Makefile.PL
$ make
$ make test
$ make install
[download]

so if you download the module to a directory called uswsqa Sys, then all you should have to do is substitute that directory for /tmp in the above instructions...

even though CPAN.pm is suppose to be much easier, i dont push it much cause i once got bit by it, but using make is usually a very easy straight foward process
