apparently this is fixed in the next release mozilla/mozjpeg#205

[Kornel]

autoreconf: command not found sounds like you simply don't have autotools installed, and you're building source from master rather than the release tarball.

If you don't have build dependencies, then in the next major release you'll see cmake: command not found instead ;)

[tcme]

@pornel yes I am a bit lazy and hope there will be binaries :)

[Deam]

@thisconnect Libtool is required for the build to work. I used homebrew to get it.

brew install libtool

EDIT:
In your case perhaps you're missing autoconf actually.. brew install autoconf

[tcme]

hi again. mozilla/mozjpeg#205 is merged!! -suitable-emoticon-here-

For imagemin-mozjpeg cosumers: should the installation process of brew install autoconf and brew install libtool be documented in the installation section of the imagemin-mozjpeg readme?

[Will O'Beirne]

Also throwing out there that #26 can also be a pain point for osx installs.

Please try the newest version, it passed the tests for macOS.
