[mariah]

The optional spkg graphviz-2.16.1.p0.spkg fails to build on skynet/eno in sage-4.7.1.alpha1:

This is due to Pango not being installed. Should we just move this to experimental since it requires the use to install some dependencies for which there aren't spkgs?

[benjaminfjones]

My opinion would be yes, move it to experimental. Many linux systems have pango installed and on platforms / systems where it's not easy to install using a package manager, it tends to be tough to configure and compile from source.

[mhansen]

Okay, then I'll set this to positive review for moving graphviz from optional to experimental.

spkg moved on server
