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.
