Sorry if this all runs together; it looks like the line breaks aren't showing up in the preview window. I got this output when running sudo cpan Scalar::Util::Numeric; thx, Josh.

There's a new CPAN.pm version (v1.9205) available!
[Current version is v1.7602]
You might want to try
install Bundle::CPAN
reload cpan
without quitting the current session. It should be a seamless upgrade
while we are running...

You're missing your C library development headers. You should install a package that has them. These are necessary to install this module because it has to compile some non-perl C code and needs to know more about your system.
I can't tell what kind of operating system you're on, but it looks like linux. If it's debian, you should be able to use apt-get to install the 'libc6-dev' package. That will contain the headers you need to compile this module. On other types of linux there will be a similarly named package.
