Hi, I don't know what a clean build is. But I've been installing LXDE from
source these days in Debian Sid.
They have all built fine, the latest code of the cited apps included.
The only exception was when I configured libfm with --enable-gtk-doc but
then I'm not sure if that's right as it has already --enable-gtk-doc-html
Not all have WORKED fine though but that's another issue (bugs were reported
to lxsession and lxpanel).
