If you re-run configure, you need to run "make clean" before
re-compiling.

If you don't need the ffmpeg option (which provides the ability to
record fly-throughs directly to AVI files, rather than writing out
individual frames then having to use a separate encoder), the easiest
option is to just not use the --with-ffmpeg option (it's disabled by
default).

If you need the ffmpeg option and don't want to recompile it, you may
occasionally need to re-fix the Makefiles. When you update a file from
CVS, any changes to the repository version are applied to the local
copy as a patch, so any changes to your local copy will normally be
preserved. However, if the changes affect the modified portion of the
files, you will get a conflict, and will have to fix the Makefiles
manually.
