Sorry.

And I answered the above.
I meant: If you only do 'make all' in a fpc svn, it is not enough for
lazarus. You have to do 'make install' or use packages. 
Lazarus can use the fpc svn directory as source directory, but the ppu
files, the fpc.cfg, the compiler, the fpc utilities, the help, ... must
be installed as normal.

The "fpc_svn" is the the fpc source directory. It contains for
example a directory 'compiler'.
