[julia-users] Error in installing Mongo package on Mac OS

Does Pkg.checkout("Homebrew") and restarting Julia make any difference? If not, 
go back to the tagged release with Pkg.free("Homebrew")

[julia-users] Error in installing Mongo package on Mac OS

2016-08-01 Thread Roger Whitney 
I am new to Julia and am trying to use the Mongo package. I am using Julia 
0.4.6 on Mac OS 10.11.6. When I try to add (or build) the package using 
Pkg.add("Mongo") or Pkg.build("Mongo")I get the error:

"Error: Cannot install mongo-c because conflicting formulae are installed.


  libbson: because mongo-c installs the libbson headers


Please `brew unlink libbson` before continuing.


Unlinking removes a formula's symlinks from 
/Users/whitney/.julia/v0.4/Homebrew/deps/usr. You can

link the formula again after the install finishes. You can --force this

install, but the build may fail or cause obscure side-effects in the

resulting software."


I then tried to unlink libbson using: Homebrew.brew(`unlink libbson`) and 
then tried building Mongo again, but had the same error.


Has anyone been able to install the Mongo package on a Mac?  Any help would 
be appreciated. There was a thread on the Mongo package about a year ago 
which ended in people claiming they were able to install the package but 
errors there seemed different.
