this happens when somebody uses a historical localconf.php from a very old
TYPO3 installation.
in these times localconf contained the line 
...[EXT][requiredExt]='cms,lang';

then services and later versioning was added to this list.
but since it was clear that adding required exts would break every
installation out there, this line was removed from default localconf years
ago (I didn't find it in 3.6.2 so I suppose it was removed between 3.5 and
3.6 when service where moved to the core)

Martin, check your localconf and remove the requiredExt line.
