### Note

The tarball expands to 'soundtouch' instead of the expected 'soundtouch-2.4.1'

Install SoundTouch by running the following commands:

### Caution

The bootstrap command below fails if the ACLOCAL environment variable is set as specified in Xorg-7. If it is used, ACLOCAL needs to be unset for this package and then reset for other packages.

    ./bootstrap &&
    ./configure --prefix=/usr \
                --docdir=/usr/share/doc/soundtouch-2.4.1 &&
    make

This package does not come with a test suite.

Now, as the `root` user:

    make install
