Hi all, I am trying to update some of the Mongo related packages, specifically the LibBSON one, and I am pretty confused as to how to deal with importing packages into my julia environment.

I have added the package from the package command prompt with `add https://github.com/pazzo83/LibBSON.jl`

This seems to add and build the package fine, however, when I go to load it in my julia prompt (i.e. `using LibBSON`), I get this error:

```julia
ERROR: LoadError: LoadError: ArgumentError: Package LibBSON does not have Libdl in its dependencies:
 - If you have LibBSON checked out for development and have
   added Libdl as a dependency but haven't updated your primary
   environment's manifest file, try `Pkg.resolve()`.
 - Otherwise you may need to report an issue with LibBSON.

```

Following the prompt, I run `Pkg.resolve()`, and this seemed to deal with that. However, as I push new commits to that repo (which i `add`ed earlier), upon running `up LibBSON` from the package command, it does not pick up the changes.  
What am I doing wrong here?

I think you meant to use `dev` instead of `add`? The [docs](https://docs.julialang.org/en/latest/stdlib/Pkg/) say this about `add`ing local packages:

> The changes would have to be committed and the packages updated in order to pull in the changes.

I do push the changes to the package, but maybe they won’t pick up updates to master even if you use `add` with the git url?

I’m pretty sure that is the case (having to do with reproducibility and such). I’m not 100% sure.  
I would try to explicitly update the package (using `pkg> up <package_name>`) and see if that fixes your issue. If it does fix your issue, then perhaps `dev` is more appropriate.

Here is variation on the problem raised by the initial poster:

I seem to be having trouble with precompilation of packages having  
Libdl as a dependency, under Julia 0.7. The problem occurs on my  
mac. On my Ubuntu machine I have no problem.

For example, consider `DataFrames`; it depends on `CodecZlib`, which  
in turn depends on `Libdl`. After a fresh 0.7 installation I do the following (session output appears below):

1. Add `CodecZlib` succesfully but with a warning like the one in the original post.

2. Add `DataFrames` without problems (but I think the warnings are now  
being supressed).

3. `using DataFrames` triggers precompilation, which is apparently  
successful (ditto warnings).

4. Restart the REPL and attempt `using DataFrames` but this time get  
the original warning and “…compilecache failed to create a usable  
precompiled cache file for DataFrames.”

5. In every session `using` triggers re-precompilation on both  
`DataFrames` and `CodecZlib` and on anything involving `Libdl`, as  
far as I can tell.

While I don’t actually get errors, the forced precompilation of many  
of my commonly used packages makes 0.7 unuseable from my point of  
view.

CodecZlib can do [https://github.com/JuliaLinearAlgebra/Arpack.jl/pull/28](https://github.com/JuliaLinearAlgebra/Arpack.jl/pull/28) to fix this issue (edit: [https://github.com/bicycle1885/CodecZlib.jl/pull/26](https://github.com/bicycle1885/CodecZlib.jl/pull/26)).

I’m not sure I understand what you did, but after updating my packages, everything is now working! Thanks!!!
