the Blackfin svn trunk has been updated to git
29b1230c7fe8191ef128a6b59e6d9a633863d3bb already (24 Apr 2009).  if
you want to try a newer snap, you can just do:
cd lib/speex
make ROOTDIR=../.. gitweb-update

but if you really want to use the 2009R1 branch, then you can simply
copy the snapshot dir over and change VER in the Makefile.  swapping
between versions at build time is insanely trivial.
