@mai, maybe you are not clever enough for this task.
Now you are totally confusing 2 different toolsets: a 3rd party FpcUpDeluxe and the "official" Lazarus installation.
When you compile Lazarus using its own makefile, obviously FPC must be properly installed at that point. You can easily test it by typing "fpc" at console.
I must blame also the people who recommend FpcUpDeluxe for total newbies. It is an advanced geeky tool, most valuable for people who cross-compile. It is not suitable for "normal" installation because it keeps both FPC and Lazarus in an isolated sandbox.
Besides, compiling Lazarus from sources is easy. There is no need to recommend a geeky FpcUpDeluxe for it. You guys have totally confused "mai" by doing so.
Better sleep over night ... maybe things start to make sense in the morning.
P.S.
FPC and Lazarus both use SVN, not CVS, for their revision control.
