This error message tells what you missed:
Running 'compile' for libxml2 2.8.0... ERROR, review 'tmp/x86_64-linux-gnu/ports/libxml2/2.8.0/compile .log' to see what happened.
*** extconf.rb failed ***
It tries to compile libxml2 but fails. Usually you need development library that contains header files to compile those dependencies.
Solution:
$ sudo apt-get install libxml2-dev
