Xilinx ISE Webpack on 64-bit Ubuntu 12.04

It's been a bit of a boring waste of effort sorting out the dogs breakfast to make this work... here's some stuff I did that will hopefully let you not loose time for the same reasons:

a) download the webpack blob, and install it.
b) to get a license, the install dialog didn't send me to their website so i logged in manually and created the free webpack license, downloaded it and then selected it
c) had to install portmap service
d) had to install libstdc++5
e) had to find libmotif3 64-bit deb and install it

floorplanner lauch script is taking forever to load and fail at this point. still trying to sort it out.

f) installed xfonts-100dpi and xfonts-75dpi as recommended in some forum

receiving RPC auth errors on the console,
receiving Wind/U Error (122) Function GetTextMetrics errors on the console

see this other guy's blog post here: http://wienker.org/blog/?p=188 for more issues/solutions

[update] got floorplanner running by following this: http://forums.xilinx.com/t5/Archived-ISE-issues/XPower-in-Linux/td-p/761 where you add some fallback fonts.

portmap rpcbind errors go away if you run rpcbind with "-wi" options instead of default "-w" option, but you'll have to lock yourself down with iptables afterwards.
