Based on this I'd say that the problem is she doesn't have a compiler
installed on her system.  Many of the newer desktop-oriented
distributions do not install a compiler by default.

She should run (from the command line):

   $ sudo apt-get install build-essential

then enter her password.  Alternatively you can use one of the graphical
software manager tools (bring up the menu search and type "software")
and install the "build-essential" package.

Here's a free tip: it is virtually never the case that the right answer
to a problem in GNU/Linux is "reinstall the operating system".

I know that refugees from Windows will often feel like that's a first
step whenever encountering a problem, but 99.99% of the time when you do
this in GNU/Linux you'll discover that you have spent a good bit of time
and effort and achieved exactly nothing (you'll have the same problem as
when you started).
