Hi Santiago, Thanks for reporting the bug. I've pushed a fix for it to the master branch, http://deb.li/rKfh
RAM was not an issue here. The buildscripts divided the number of available processors by 2, however that obviously wouldn't work for a single processor so I added a check to not do that when processors < 2. The default is 1, which is why they must have added this. Regards, Chirayu
