Hi, this is not urgent. I was not going to report it, but I thought developers might want to know. If you want to know more reply what information you would like, and I'll try to get it for you. I do not intend to use the compiled game in place however. Unless it is of interest for development or helping with other bugs, no need to reply.
I am using Ubuntu 16.04. Compiling 0.4.15 with typical options and running in place, the game compiles and loads however any added mods do not load textures. For example I test it with the Dice2 mod. The mod reports no errors, but textures simply do not load. The mod is properly installed I think. I have not tested this mod with an installed 0.4.15, just the one I compiled and ran 'In place'.
