Question
I've been trying to install XML::Simple on Ubuntu 12.10 for the past two hours or so and have officially run out of ideas. It's failing at the XML::Parser.
I've done an

Seems to be telling me that it's unable to find expat.h, but I'm not sure why or how, considering expat is installed? I tried to apt expat-devel, but it appears not to be a package in apt. Any ideas would be greatly appreciated. :)
EDIT: I seemed to have been simply trying to install the wrong package. -.- It's always the little things. Much thanks to those who answered!
Solution
Another way to get to the same information which @Moritz Bunkus has pointed out above.
ubuntu:~$ apt-cache search expat
expat - XML parsing C library - example application
libexpat1 - XML parsing C library - runtime library
libexpat1-dev - XML parsing C library - development kit
The third one in the result set is what you are looking for.
OTHER TIPS
Adding to the other answers, here's how to install the expat dependency on CentOS/RHEL:
yum install expat-devel
You need to install the Expat library and its development headers. For DebUbuntu this means libexpat1-dev as well as those distros often split their libraries into two packages: one for the runtime components (shared libraries, data files, general documentation), one for the development components (static libraries, header files, development documentation).
Just in case, using Debian Jessie I had to install libexpat1-dev by executing apt-get install libexpat1-dev
I only managed to install it by downloading it from cpan and manually editing the Makefile.pl inside to correctly pointing to the EXPATLIBPATH and EXPATINCPATH.
See this post for more detailed instructions.
