手機開發過程中，需要運行高通的一個腳本parser.pl，但是這個腳本依賴一個LibXML的庫，怎麼都裝不上去。

Checking for ability to link against libxml2...libxml2, zlib, and/or the Math library (-lm) have not been found.
Try setting LIBS and INC values on the command line
Or get libxml2 from
http://xmlsoft.org/
If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.
Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.

但是我確實是安裝了libxml2了
$ sw/device/qcom/common/display/tools$ dpkg -l |grep libxml2

ii libxml2:i386 2.9.1+dfsg1-3ubuntu4.6 i386 GNOME XML library
ii libxml2-utils 2.9.1+dfsg1-3ubuntu4.6 amd64 XML utilities
雖然裝上了libxml2，但是cpan install XML::LibXML時找不到。
最終在StackOverFlow上找到了解決方法

Why do you want to use CPAN for this anyway? It is typically very bad idea to install CPAN packages if you have native packages provided by standard operating system installer.
Ubuntu provides a lot of Perl packages natively, with following naming convention: package name always starts with lib, then Perl package name like XML::LibXML is converted to lower case and :: replaced to dash - (XML::LibXML => xml-libxml), and finally -perl suffix is added. In other words, native package name for XML::LibXML would be libxml-libxml-perl.
So, in your case, you simply run this command and it will pull all necessary dependencies automatically:
Ubuntu提供了一系列的經過轉化的Perl包，我們可以通過apt-get而不是cpan的方式安裝這些包。
這些包盒cpan的包的名字是這樣轉換的：大寫字母全部換成小寫，符號::換成-。例如：XML::LibXML轉換成libxml-libxml-perl。
$ sudo apt-get install libxml-libxml-perl
If you don't like this package for any reason you can uninstall it with sudo apt-get remove. If you use CPAN, it is very difficult to uninstall it reliably.
