@Kruug how much Ram is on your dedicated Debian server/VPS could also be a problem with libboost
try this: sudo apt-get install libboost1.53-all-dev
Let me know if the changes you made to git worked on your end.
Like I said, libboost is all up-to-date (even re-ran your command, nothing was updated).
It was looking for the MinGW libraries, and every path for the qmake was Windows-based (references to C:\). If we're going to follow what other coins do, we should be making our GitHub repository line up with a *nix-based build, and not leaving Windows references in the source, unless they are commented to out for faster updated builds when the code is updated.
