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 &&

            --docdir=/usr/share/doc/soundtouch-2.4.1 &&
make

This package does not come with a test suite.

Now, as the root user:
