Hi Niko,

I noticed that your recent changes have broken the translation of 
pypy-jvm on tuatara, because now pypy-jvm requires jna, and it's not 
installed there.

I tried to download jna from the web but I failed to understand what 
package(s) I need; do I need only jna.jar and/or the platform specific jar?

I wonder whether it might make sense to include the .jar directly in our 
svn repo, to drop the external dependency on jna and simplify the life 
of those that want to build pypy-jvm by themselves.

ciao Anto
