Bug#760162: shogun: FTBFS[kfreebsd]: graphviz dot tool may hang

[Steven Chamberlain <steven@pyro.eu.org>]

Package: shogun
Version: 3.2.0-7.1
Severity: serious
User: debian-bsd@lists.debian.org

Hi,

https://buildd.debian.org/status/fetch.php?pkg=shogun&arch=kfreebsd-i386&ver=3.2.0-7.1&stamp=1409345492 :
| Running dot for graph 746/775
| Running dot for graph 747/775
| Running dot for graph 748/775
| E: Caught signal ‘Terminated’: terminating immediately

This does look like a bug in graphviz running with multiple threads, but
I really must ask:

Why is documentation built on *every* architecture?  The shogun-doc
packages are arch: all?

from debian/rules
| override_dh_install:
|         $(MAKE) -C doc doc

shouldn't this be only done within a build-indep target?  And that way
the Build-Depends could be reduced to not include texlive and such.

Thanks.
