/usr/local and gs again

[Ethan Benson <erbenson@alaska.net>]

todays update included a new gs again, version 5.10-9 

on install i saw this:

Setting up gs (5.10-9) ...
mkdir: cannot create directory `/usr/local/lib/ghostscript': Read-only file system
mkdir: cannot create directory `/usr/local/lib/ghostscript': Read-only file system
mkdir: cannot create directory `/usr/local/lib/ghostscript': Read-only file system

is it or is it not supposed to be creating these directories in
/usr/local?

(on my system /usr/local is its own partition (as is /usr) both are
readonly, and apt is only taught how to remount /usr not /usr/local)

thanks
