Error in library libgmt installation

[mforets]

Hi,
do you have some idea how to fix the error below?

julia> using GMT

julia> plot(collect(1:10),rand(10), lw=1, lc="blue", fmt="png", marker="square",
            markeredgecolor=0, size=0.2, markerfacecolor="red", title="Hello World",
            x_label="Spoons", y_label="Forks", show=true)

My system is a Mac OSX 10.11.6, and i did a $ brew install gmt. Strangely enough, the plot command of above was working until i updated some packages with Pkg.update(). Perhaps i should try deleting and reinstalling the command line tool and the julia package?

Ok, What is happening is the following. To the master version of GMT.jl slipped one instruction that works only with the (soon) future GMT6. Think I fixed this case so try do a Pkg.checkout("GMT").

Great, thanks. Now i'm getting a different error (perhaps an issue with my julia version? Version 0.6.1 (2017-10-24 22:15 UTC))

Hmm, sorry my fault. Please update and try again. But notice that the master version may fail time to time.
For example, to run the tests I'm obliged to use the GMT6dev version and that is set in the GMT.jl file. You'll see there a line with

const GMTver = 5.0
or
const GMTver = 6.0

Since you have GMT5 you want the first setting but sometimes (e.g. for running the tests) I need to set it to 6.0. When you have the wrong combination julia will probably crash.

Great! It works now, thanks for the help.
