I have now setup an Arch VM with fluxbox as windows manager, using the minimum system I could get working. With that, only the following in bld_prepare was needed to build Cinelerra-gg: "arch") pacman -Syu gtk2 nasm yasm cmake fftw patchelf boost boost-libs \ base-devel libvdpau libva perl-xml-parser perl-carp libogg texinfo \ libsndfile ;; Using fluxbox, the ram usage was impressive small: while building CinGG, it used less than 200 MB RAM, according to "free -h" . Tomorrow I'll add the manual without tex-full, that pulls in far too much. The used disk space after building does not change much: 8 - 9 G, between 2 times ARCH with XFCE desktop, and one with fluxbox. It seems to me the other platforms pull in far too much in bld_prepare.shfor building CinGG. MatN PS None of the 3 Arch installs in a VM went without hitches. Several time I had to kill VirtualBox because the desktop froze, usually after getting a lot of "enter" keystrokes, or after doing "fdisk -l" during the initial stages of the install process. Could be a VBOX isssue, of course, but none of the other distro VMs had that that I can remember.
