This is an upgrade ebuild to fvwm 2.4.8, and patches to Makefiles to enable the symlinks to fvwm and fvwm-root (which otherwise tripped the sandbox).
Created attachment 2732 [details] ebuild and patches; shar archive
These patches have also been submitted to fvwm; see http://www.fvwm.org/cgi-bin/fvwm-bug/incoming?id=907
