Subject: perf trace: Problems initializing symbol libraries!

Hey all,

I'm getting the following error when trying to run `perf trace` built from 
acme's perf/core branch on an Ubuntu 16.04 machine:

$ perf trace
Problems initializing symbol libraries!

strace shows this at the end:

...
lstat("/proc", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
lstat("/proc/kallsyms", {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
write(2, "Problems initializing symbol lib"..., 40Problems initializing symbol 
libraries!
) = 40
exit_group(244) 

Is something wrong with my /proc/kallsyms? Can someone tell me what the 
problems are that are being encountered?

Thanks
