 > I have to add, I'm on PPC under Mac OSX 10.4.11.

 Attached are patches that build on the recommendations above to allow
 ffmpeg to build on my PPC under 10.4.11.
 The Portfile patch is relative to the latest in SVN as of this morning and
 includes one patch file in addition
 to the one suggested by the maintainer above.  The changes do the
 following:

 1) Increment the svn revision for the libswscale code to r27349 to pick up
 a fix for the altivec compile problem
 on Tiger PPC using gcc 4.0.1 noted immediately above

 2) Patch configure to remove the -current_version and
 -compatibility_version options from the SHFLAGS definition
 which is used for the shared library build command.  This disables library
 versioning and compatibility checking
 but allows the build to proceed without error.  Darwin does not allow
 either of these to be zero but the current
 version numbers for libswscale and avfilter cause one or both of these to
 be zero.  Basically, as the system
 currently works, version numbers less than 1.0.0 will not work.
 libswscale is 0.5.1 and avfilter is 0.0.0.
 Probably something to report upstream for resolution.
