I think I figured it out - at least partially - it's really fun...

Anyhow I added a #phases modification to the package definition, setup a 
local directory channel with the package definition. Then could add the 
package module and the icewm package to system config, reconfigure and 
it's there with other WMs.

This is what I ended up with for reference:

    (description "IceWM is a window manager for the X Window System. The 
goal
of IceWM is speed, simplicity, and not getting in the user’s way. It 
comes
with a taskbar with pager, global and per-window keybindings and a 
dynamic
menu system. Application windows can be managed by keyboard and mouse. 
Windows
can be iconified to the taskbar, to the tray, to the desktop or be made
hidden. They are controllable by a quick switch window (Alt+Tab) and in 
a
window list. A handful of configurable focus models are
menu-selectable. Setups with multiple monitors are supported by RandR 
and
Xinerama. IceWM is very configurable, themeable and well documented. It
includes an optional external background wallpaper manager with 
transparency
support, a simple session manager and a system tray.")

--8<---------------cut here---------------end--------------->8---

It might be incomplete though - maybe it's lacking some services or 
something, as the IceWM that starts up now does not have full Settings 
options - like Display settings for instance - as the IceWM from Ubuntu 
Mate has on the same machine from a parallel boot. It might be due to 
some concrete configurations etc - I'll explore. Or it might be due to 
having not declared something helpful in the package definition... If 
anyone has ideas, I'll be happy to hear those and test them...
