I have been trying to build l4re and have the following issue. I am building l4re snapshot with some other modules not included in the package. The issue is when i am building moe, and it has not been changed and is the one that is included in the package. I am  building it on a virtualbox running xubuntu 15.04 (in case it helps to find the issue or could be the problem). I am not sure how to move ahead with this problem and am curious if anyone has ideas or pointers to look for/at.
