On OS/X 10.4 (and possibly other versions), the generated libtool does not directly accept the "- framework Accelerate" option. Instead, it must be invoked as "-XCClinker -framework - XCClinker Accelerate". Here's a patch to fix that.

Build fails on 10.5.8 as well. And this bug has been around for nearly two years already. Which is a pretty good sign that this project is abandoned.

Build failure on OS X 10.5.8 is

On 10.6 I needed this diff along with the above

I still get

I'm getting some build errors on OS X (10.5.8 PPC) as well. Please see the attached log for full info, but it looks like similar undefined symbols.

Try this command to regenerate configure file after the above.

$ autoconf
