@staticfloat, is there a typical cause for the "installed but not linked" issue?

[staticfloat]

That notice is normal. What does BinDeps.debug("GraphViz") say?

[mlubin]

A number of users have experienced this, here's a sample error:

julia> dlopen("/Users/tmak/.julia/v0.3/Homebrew/deps/usr/Cellar/graphviz/2.38.0/lib/libgvc")
ERROR: could not load module /Users/tmak/.julia/v0.3/Homebrew/deps/usr/Cellar/graphviz/2.38.0/lib/libgvc: dlopen(/Users/tmak/.julia/v0.3/Homebrew/deps/usr/Cellar/graphviz/2.38.0/lib/libgvc.dylib, 1): Library not loaded: /Users/tmak/.julia/v0.3/Homebrew/deps/usr/lib/libltdl.7.dylib

There's no libltdl.7.dylib installed.

[mlubin]

@staticfloat, does libtool need to be added as a dependency of graphviz?

[staticfloat]

Oh bother. This is probably one of those things where if libtool is present, it will link it in, but it doesn't declare it as an actual dependency. I'll fix this.

[staticfloat]

New bottle up. Want to tell the users to try these new bottles after a Pkg.update()?

[mlubin]

Working now, thanks!

There's now a warning about pango:

(process:13571): Pango-CRITICAL **: No modules found:
No builtin or dynamically loaded modules were found.
PangoFc will not work correctly.
This probably means there was an error in the creation of:
  '/usr/local/Cellar/pango/1.36.8/etc/pango/pango.modules'
You should create this file by running:
  pango-querymodules > '/usr/local/Cellar/pango/1.36.8/etc/pango/pango.modules'

(process:13571): Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderCoreText', script='common'

Closing since unrelated to GraphViz.

[staticfloat]

Actually, I think this is still related to GraphViz. Since this package uses pango, but doesn't call using Cairo, we need to duplicate this initialization routine here.

[foebu]

I still got the problem:
Warning: graphviz-2.38.0 already installed, it's just not linked

The strange thing is that on mavericks the stable version should be 2.36, while brew tries to install the 2.38.

[staticfloat]

Hey @foebu, that warning message is normal, don't worry about it. Note that the version of graphviz that is getting installed is coming from this homebrew tap, which has 2.38 as the stable version. Beyond that message, are there any problems with your installation?

[foebu]

Hi @staticfloat, apparently no. Even though I got some issues with pygraphviz library and python 3, due to the fact that the library couldn't locate graphviz. But I think that's not your problem, but their problem :)

[staticfloat]

Yep, you're going to have to point pygraphviz at the library somehow, perhaps with DYLD_FALLBACK_LIBRARY_PATH or some such, because its in a very non-standard location (inside your .julia directory). That's the best tip I can give you.
