Bug#462292: gjdoc: fails to upgrade when /proc is not mounted

[Vagrant Cascadian]

Package: gjdoc
Version: 0.7.8-7
Severity: normal

when upgrading gjdoc in a chroot environment without /proc mounted, i
get the following string of errors:

Preparing to replace gjdoc 0.7.8-6 (using .../gjdoc_0.7.8-7_i386.deb) ...

E: Sub-process /usr/bin/dpkg returned an error code (1)

it would be nice if gjdoc didn't require /proc to be mounted during
upgrades.

live well,
