Ah, my fault...

I added my hook before base in HOOKS array. This way bin was a real directory
instead of a symlink to usr/bin.

(Note to self: Never do silly things. ;)
main(a){char*c=/*    Schoene Gruesse                         */"B?IJj;MEH"
"CX:;",b;for(a/*    Chris           get my mail address:    */=0;b=c[a++];)
putchar(b-1/(/*               gcc -o sig sig.c && ./sig    */b/42*2-3)*42);}
