Dang.
I've download libreoffice source code, and tried to compile it.
It presented some errors which I was able to solve, until it appeared errors related to Java.
I downloaded, compiled and installed Java RunTime 1.7.0_u45 and it passed the first check for java, then i got stopped at javac... the ./configure couldnt find it. And this is where i hit a wall. Tried to compile openjdk6, but it asks me for ANT... downloaded ANT source code and when compiling it, asks for javac.... ok... i'm about to quit.
If you have any ideas I'm all ears/eyes.
Thanks and regards.
