The system unit is needed to compile any unit. If some units were
compiled, then there are two possibilities:
- You have messed up your FPC install.
- You found a bug in the compiler, which is triggered by the Indy
  package.

It should never write that file. Unless you changed the package
fcl.lpk.

A normal user can not change files under /usr/
That's why the IDE compiles under ~/.lazarus/bin

Close IDE, delete ~/.lazarus, uninstall lazarus, fpc, fpc-src. Install
fpc-2.6.0-2.fc17.x86_64.rpm
fpc-src-2.6.0-2.fc17.x86_64.rpm
lazarus-1.0.4-0.x86_64.rpm
Install package lazdaemon.
