Unable to run sample on Linux

[PMunch]

After fixing some minor build issues I was able to build the sample binary, but when I try to run it I just get a crash with:

Traceback (most recent call last)
/tmp/nimCEF/simple.nim(245) simple
/tmp/nimCEF/simple.nim(236) main
/usr/lib/nim/core/macros.nim(567) ncInitialize
SIGSEGV: Illegal storage access. (Attempt to read from nil?)

Any idea what is going on?
