I actually found that gentoo upstream ebuilds actually provide LxQt 0.14.1 including pcmanfm-qt and qterminal and stuff.
Now, i actually need to find out how to/manage to get them together with my fresh built funtoo 1.3-kit.
(Well, at least, having a funtoo within funtoo is sorta fun.. chroot ftw. ;))
P.s.: The linked git repo from shadow53 seems to be down sadly. ?
