The DLL hell is so bad mainly because the DLLs may get out of sync
easily, breaking API and ABI compatibility. Sometimes programmers don't
see that and the programs run strangelly, bugged, crashing randomly, or
misteriously won't compile giving away spurious errors deep inside
libraries. Worse, is possible to create programs which relies in some
bugs introduced by the DLL hell. This is even worser to novices.
As an example. Imagine if someone is building a game with Allegro-core
DLL 4.3.5, however using AllegroBMP DLL 4.3.3 and AllegroWAV DLL 4.3.6,
things will not work. If the user recompile each DLL, but for some
reason forget to recompile one or recompile to a different version, we
will get a DLL hell.
