unmesha@client:/usr/local/mahout/mahout-distribution-0.9$ ls
bin         core          examples     LICENSE.txt  math-scala  pom.xml     src buildtools  distribution  integration  math         NOTICE.txt  README.txt  target
unmesha@client:/usr/local/mahout/mahout-distribution-0.9$mvn install

Wait untill mahout is build. It would perform some tests also.It is recommended to complete the test for the first time.Later you can skip the test using

mvn install -Dmaven.test.skip=true

Once the tests are done and the mahout is built , we get a success message.
