LilyDev4 and Guile2.2 ?

[Paul]

Hi all,

Having been unsuccessful at getting LilyDev5 running on my laptop using 
VirtualBox, I'm wondering how it would work to create a virtual machine 
with LilyDev4 (which is working for me) and then uninstalling guile1.8 
and installing guile2.2.

Is this a fool's errand?  I'm new to this dependency hell business, 
would be a good induction, maybe too good?

Thanks for any advice,
-Paul
