Hi. Thanks for this! It's very informative. I've run into a glitch in using it, tho. I'm trying to install snappy 1.0.5 for use with Hadoop 1.0.3 on Ubuntu 12.04 LTS. I'm getting a build error from maven indicating that no pom.xml exists:

superuser@zdog:/usr/local# mvn clean package -Dsnappy.prefix=$PWD/snapply

I get the same missing pom.xml message when I don't use the clean option for mvn.
