Same problem. I decided to try vibed on vps.me and after `dub init web1 vibe.d` it's try to compile but fall at low memory (I have only 384 MB on server).
I tried the single-file compilation mode, it's begin to build all but then fail with error about low memory.
I do not have another copy of linux, and I am afraid that they would be incompatibility, is there other way to run dub on such config?
