>Description:
I just updated pkgsrc on my amd64 workstation, and noticed some errors
messages with dotty command from graphviz package when processing
pkgdepgraph output.

njoly@lanfeust [~]> pkgdepgraph | dotty -
dotty.lefty: draw language parser error: 18
dotty.lefty: draw language parser error: 18
dotty.lefty: draw language parser error: 18
[...]
dotty.lefty: draw language parser error: 18
dotty.lefty: draw language parser error: 18
dotty.lefty: draw language parser error: 18

It seems to work, except that ellipses around packages names are not
displayed anymore in generated graph.

njoly@lanfeust [~]> pkg_info | grep -e graphviz -e pkgdepgraph
pkgdepgraph-2.8     Visual representation of installed NetBSD packages
graphviz-2.12nb4    Graph Drawing Programs from AT&T Research and Lucent Bell 
Labs
>How-To-Repeat:
Run `pkgdepgraph | dotty -'
