> For the next week I study how to put Stéphane Rollandin muO amazing project

it will not be easy :)

I'm still developing in a 3.8 image; you should probably wait a little 
as I will try to port muO to the upcoming 4.0 or 4.1 as soon as I can.

moreover, muO is a very big system highly susceptible to conflict with 
other packages...

anyway, thanks for your long-standing interest !



regards,

Stef
