TK dependency woes

[Lewis Levin]

It is a bit beyond me to debug what follows.

My Python build works fine.  PyPlot within Julia works fine.

 I suspect the problem is with the ImageView package.

I'd seen that reference you suggested and I don't really want to change all the dependencies.  

Something in the latest mods of ImageView or Images broke things.  All I've done is to reinstall Julia 0.4.6 and all packages.  All of the dependencies:  Python, TK, tcl have been left as is.

If I do using Images, ImageView from the julia command line and then include a script all works.  If I include the script at the command line (the script contains using Images, ImageView) then it fails.

Why should their be a difference?

[Lewis Levin]

Deeper view of the problem.  Either code in Julia packages or OS X itself can't resolve symlinks properly.

If you look at the conflict message, the conflict is between libtk.dylib and /Library/Frameworks/Tk.framework/Versions/8.5/Tk.

Here is the absurdity:  libtk.dylib is a symlink to libtk8.5.dylib which is a symlink to /Library/Frameworks/Tk.framework/Versions/8.5/Tk.  

So, there is only ONE version of TK installed.  The problem is the series of symlinks.

Unfortunately, due to OS X security it appears to be impossible to modify things in /usr/lib.  I have tried with sudo and the OS still blocks.

[Lewis Levin]

Further:  there is nothing about the command line.  If you include("script.jl") in julia, the first time it fails.  Immediately, run it a second time and it works.

Go figure.

This is still not really as it should be and looking for any further help.
