Given encouraging replies to my earlier posting I merged monotone
onto my Gentoo box.  This is a fairly vanilla 2004.3 installation.
The only things I did were to copy the monotone-0.16.ebuild to my
overlay tree and to add a ~amd64 keyword.  From there on the build
proceeded smoothly.  Sadly the result gets an immediate seg fault.
See backtrace below.

By comparison merging darcs went equally smoothly and delivered a
working result.  I have used darcs to access wmii per this URL:
