Re: [head tinderbox] failure on amd64/amd64

Hi David,
Thank you for looking into this issue.
Also many thanks for the fix you submitted for amd64.
I'll try these days to replace this usage of libdisk with libgeom.
Please find below.

For sure Harti will have a better explanation but I can try to respond
to this question.
The shared lib produced from this directory is used by the bsnmpd
agent to be loaded at runtime. When this shared lib is loaded we will
see the undefined symbols.  One way to control when this so is loaded
is via the agent config file (usually located in /etc).
