Jenkins : Why do we need to wait so much time

[Philippe Mouawad]

Hello,

I see in Jenkins  this message since many weeks:
Note: currently only builds on ubuntu1 Builds on ubuntu 2,3,5 fail with:
Uncaught Exception java.lang.UnsatisfiedLinkError:
/home/hudson/tools/java/jdk1.6.0_27-32/jre/lib/i386/xawt/libmawt.so:
libXext.so.6: cannot open shared object file: No such file or directory.

How can it be fixed ?
