Since these are freeciv independent there are other sources:

http://farside.ph.utexas.edu/teaching/329/lectures/node35.html
http://oucsace.cs.ohiou.edu/~bhumphre/makefile.html
http://www.cs.utah.edu/dept/old/texinfo/configure/configure.html#SEC1

However note that while the freeciv build-system is based on makefiles
it is a lot more complex that the examples mentioned above. It shares
the same simple rules mentioned above but is larger.

Running "make".

That you don't use an up-to-date CVS version.

Please tell us exactly what you are typing and what outputs these
commands write. It is the easiest way.

Yes it should work out-of-the-box with linux.

So what you please do is that untar your source, "cd" do the dir and
than type "./configure && make" and post all output. We will see what
problems you have this way.
