Edit: Looks like it's just from one of my servers. Also getting this error when installing on a DigitalOcean VPS:
runtime: panic before malloc heap initialized
fatal error: runtime: cannot allocate heap metadata
From previous experience, I'm pretty sure the problem is that when you compile with Go 1.1 your program's VM commit charge is much larger (~500M) than it was with Go 1.0 (~70M):

Hence it runs out of memory on low-memory systems. Rebuild Go 1.1 from source with this patch applied:

Then rebuild your program and it should be fixed.
