looks like audiofile no longer installs "audiofile-config" (just a .pc file), but normalize only searches for the config script, and so building it fails configure:24394: checking for audiofile-config configure:24425: result: no configure:24433: checking for Audio File Library - version >= 0.2.2 configure:24563: result: no configure:24693: error: --with-audiofile specified, but audiofile library not found you can see this in AM_PATH_AUDIOFILE in the aclocal.m4
Fixed in the latest revbump in CVS. I bumped normalize to depend on >=audiofile-0.3.1 in order to simplify checking for audiofile only using pkgconfig.
