[fpc-pascal] sysutils not found, haunting me

[L505]

"Sysutils not found" is haunting me. Some of my programs compile fine, some
don't.. randomly. So basically sometimes sysutils works, sometimes doesn't (I
have also being playing around with compiler settings, and once in a while
deleting a ppu file or renaming it to ppu.old can do the trick)

Here is my latest problem

(normal if you did not specifiy a source file to be compiled)

Any idea what the problem is ? I'm using lazarus, but I tried the compiler at
the command line.. with the -va option, that's what I got. (didn't paste entire
snippet).
