Centipeed,

    Out of the box Ubuntu lacks developers tools: compilers,
libraries, etc. Please post the output of ./configure if you want
peopple to take a deeper look at what is missing in your setup. If you
are newbye to linux I would strongly suggest to stick to version 1.8.4
that you can install using apt (download the package and copy it to
your laptop), unless you really need the features available in 1.8.5
