All you need is the langtools repository.

First grab the VM, the best is to look which beta to use here
http://hg.openjdk.java.net/lambda/lambda/hotspot/
and grab the corresponding binary build here
http://dlc.sun.com.edgesuite.net/jdk7/binaries/index.html

If you don't find the correct build number, take a more recent one,
it should work.

Now compile the compiler source,
get the langtools repository:
hg clone http://hg.openjdk.java.net/lambda/lambda/langtools
The good news it that this repository compiles with ant,
so in directory 'make', run
   ant -Dboot.java.home=<path to jdk1.7.0 beta>
it creates a classes.jar in a dist subrepository.

To run the compiler:
<path to jdk1.7.0 beta>/bin/java -cp classes.jar 
com.sun.tools.javac.Main <your source.java>

and to run your code:
<path to jdk1.7.0 beta>/bin/java -cp classes.jar:. <your class>

You need to put the classes.jar in the classpath because the current 
prototype
has runtime dependencies that are not available in a binary build.

That's all.
