Install autoreconf on OS X v10.7 (Lion)?

Question

If you are using Homebrew, try

brew install automake

Which should also install autoconf and allow rvm to finish installing.

If you want to do this using MacPorts instead of Homebrew, you can do:

sudo port install automake autoconf libtool

I had the same problem and this solved it for me.

If you're using brew, then the autoreconf utility is part of the autoconf package, so install it via:

brew install autoconf

If the problem persists, consider either reinstall or link it again. Use locate autoreconf to find out where it is.

Also check if /usr/local/bin/autoreconf exists (and is linked into the right place), and you've the /usr/local/bin path added in your /etc/paths file.

By downloading the .pkg file from MacPorts and installing it, it does the trick for me.
