perl – 如何在ubuntu 11.04上安装XML :: LibXML？

$sudo cpanm XML::LibXML
--> Working on XML::LibXML
Fetching http://www.cpan.org/authors/id/S/SH/SHLOMIF/XML-LibXML-2.0014.tar.gz ... OK
Configuring XML-LibXML-2.0014 ... N/A
! Configure failed for XML-LibXML-2.0014. See /home/kahmed/.cpanm/build.log for details.

细节：

Unpacking XML-LibXML-2.0014.tar.gz
Entering XML-LibXML-2.0014
Checking configure dependencies from META.yml
Checking if you have ExtUtils::MakeMaker 0 ... Yes (6.55_02)
Configuring XML-LibXML-2.0014
Running Makefile.PL
enable native perl UTF8
running xml2-config...ok (2.9.0)
Checking for ability to link against xml2...no
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.
-> N/A
-> FAIL Configure failed for XML-LibXML-2.0014. See /home/kahmed/.cpanm/build.log for details.

我尝试手动安装libxml2，但仍然遇到同样的问题。

另外，我检查了libxml2-dev：

sudo apt-get install libxml2-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libxml2-dev is already the newest version.
