 The patch was not reviewed and since libspeex is not completely outdated,
 we should really allow installation without jumping through the pkg-config
 hole.

 Could you elaborate how the patch made configure faster or how the
 workaround would make it slower?

 I don't think it is faster and calling removing a feature being more
 reliable is hard to understand for me.

 I never install FFmpeg.

 yasm is not needed on arm and powerpc.

 This does not even work on my development system and it certainly doesn't
 work for people using servers where they are not admins.
 But I meant using pkg-config not installing it.

 user already did something way more complex than {{{export
 PKG_CONFIG_PATH=/some/path}}}.

 I consider this at least a magnitude more difficult than setting a path.

 It is needed for my workflow and was very often requested by users on the
 user mailing list.
