Re: [julia-users] pre-compile with userimg.jl instructions

[Tony Kelman]

You actually don't have to build from source, there is a build_sysimg.jl script 
that has instructions for rebuilding the system image in a binary. This script 
had regressed a bit on some 0.4 releases, try the latest 0.4.5 release and it 
should be working again across platforms.
