Hi 
There are pre-built versions available for download. The extra
efficiencies gained by doing the build yourself is unlikely to be
worth the hassle. it is a lot easier to just download the main
installer, language-pack and "in-built help".
However, please let us know which Operating System you are using and
we might be able to help. Are you on Slackware, Xp, Win7, Ubuntu, Mac
or which?
I suspect the devs irc channel or mailing list might be more helpful
if you really do need to do the build but they will want to know which
system you are using and whether you have done any builds of anything
else before.
Regards from
Tom
