=== message truncated ===

I built 0.9.73-SVN and it seems to work.  However,
when starting in X11 mode, I get a white X window
until the OS X desktop comes up (no Tux hugging the
apple splashscreen).   If I set molrc.video to start
in console mode with the line,

start_on_console:       yes

then I get the Tux hugging the apple splashscreen.

Regardless, I can switch back and forth between X11
and console modes and all is well so it appears there
may be a bug in the released tarball version of mol.
