Julia can't find library

[patcollis34]

Hey @wildart I don't know if this is because I'm a noob or not but installing using
pkg> add https://github.com/wildart/LMDB.jl.git#v0.1.0 and then I run Pkg.build("LMDB") and I get an error saying that:
ERROR: LoadError: IOError: could not spawn ldconfig -p: no such file or directory (ENOENT)

I can't tell if this a backwards compatibility issue or if I am missing a base package or not?
