All tests fail with an error message similar to this:

Can't load '.../blib/arch/auto/XML/Parser/Expat/Expat.so' for module
XML::Parser::Expat: .../blib/arch/auto/XML/Parser/Expat/Expat.so:
undefined symbol: XML_SetCommentHandler at
.../perl-5.12.3/lib/5.12.3/x86_64-linux/DynaLoader.pm line 200.

This is despite the most recent version of the libexpat1-dev package
being installed as per the README:

# apt-get install libexpat1-dev
...
libexpat1-dev is already the newest version.

(1) what is the output of

  gcc --version

I suspect you do not have gcc 4.4 anymore

(2) Could you try

  perl Makefile.PL EXPATLIBPATH=/usr/lib/x86_64-linux-gnu

This works a little better, without the previous warnings:

$ perl Makefile.PL EXPATLIBPATH=/usr/lib/x86_64-linux-gnu
Checking if your kit is complete...
Looks good

"make" still shows some warnings:

but all tests now succeed:
