These libraries were modified from the originals.

First, they were generated by the bundled makefile, using:

```
make 64bit
```

Modifying the id and import paths was no longer necessary, as they
already use @rpath now.

As of editing, they are:

BASS		2.4.17
BASSMIDI	2.4.14.1
BASSFLAC	2.4.5.3
BASSOPUS	2.4.2.3
BASS_MPC	2.4.1.2
