what should i do please help
It's trying to call javac, the java compiler. This isn't installed as part of the java runtime environment (JRE).
On ubuntu I believe the package with the compiler has a jdk suffix, try:
sudo apt-get install openjdk-6-jdk
You may want to change that '6' to a '7' to upgrade your java installation.
sudo ... -- I've edited this in. If you can't do that because this isn't your computer, ask a question, "How can I install a java compiler to my home directory?" and I'll answer that.
