Julia : JLD package doesn't work when running Julia development version

The current version of Julia is 0.4.6. I, however, am running the development version 0.5. Suddenly JLD doesn't work. It's installed and updated. Yesterday I compiled code using JLD but this morning it doesn't work. 

julia> using JLD

When using the development version of Julia, you need to use the development versions of the packages (which works for packages where the developer keeps master up-to-date but hasn't tagged yet). If you run Pkg.checkout("JLD") to checkout master, JLD should work (works on my machine. Note you may need to Pkg.update() before checking out, and you may need to quit Julia and re-open it to recompile the new version).

But as a word of caution, don't use the development versions of Julia as a way to test things out. Remember, the language is still in alpha and there is no guarantee that the package ecosystem or Julia itself will work with the daily master. The dailies are good for working on the language and preparing packages for the next version (and being ballsy I guess).

Well, you're using Julia 0.5 which is still in development. If you switch to 0.4.6 then it should be fine. I'm using that and JLD works fine for me. You could also trying running Pkg.update() closing Julia, then reopening, to see if that helps.
