Re: the Richmond saga continues

[steven james <pyro@linuxlabs.com>]

Greetings,

I am still looking at the scripts, but in the mean while, I have made a
few mods (again) to the library setup to compensate for the changes to

perl is dependant on several affected libs. hopefully, this will make it
happy.

G'day,
sjames
