Install Autoconf and Automake on OS X Mountain Lion

# Install autoconf, automake and libtool smoothly on Mac OS X.

@hainesc: I like your script. However, it seems that now the URL added icons, so the AUTOMAKE_VERSION and AUTOTOOL_VERSION variables are wrong:

>curl -fL http://ftpmirror.gnu.org/automake | grep -E "automake.*tar.gz" | grep -vE "sig|asc" | awk -F \" '{print $2}' | sed 's/automake-//g' | sed 's/.tar.gz//g' | sort | tail -n 1
/icons/compressed.gif

Changing the awk argument from $2 to $6 fixes this

>curl -fL http://ftpmirror.gnu.org/automake | grep -E "automake.*tar.gz" | grep -vE "sig|asc" | awk -F \" '{print $6}' | sed 's/automake-//g' | sed 's/.tar.gz//g' | sort | tail -n 1
1.9.6

This returns 1.9.6 but the latest version has two digits, so I modified the sort with this tip, so this parsing works:

>curl -fL http://ftpmirror.gnu.org/automake | grep -E "automake.*tar.gz" | grep -vE "sig|asc" | awk -F \" '{print $6}' | sed 's/automake-//g' | sed 's/.tar.gz//g' | sort -f -t . -k 1,1 -k 2,2n -k 3,3n -k 4,4n | tail -n 1
1.16.1

With the version number set at "/icons/compressed.gif", the installation fails and AUTOMAKE_ERROR and LIBTOOL_ERROR are empty, which removes the left-hand side in this comparison:

[ $AUTOMAKE_ERROR -ne 0 ];
-bash: [: -ne: unary operator expected

I added an else condition and placed the change of directory and removal of the temporary directory outside the condition, so they are always executed.

Here is my revision of hainesc's code:

# Install autotools, including autoconf, automake and libtool on Mac OS X.
BUILD_DIR=~/autotools # or wherever you'd like to build

# Get the latest version of automake and libtool because they have no latest symbol link.
AUTOMAKE_VERSION=$(curl -fL http://ftpmirror.gnu.org/automake | grep -E "automake.*tar.gz" | grep -vE "sig|asc" | awk -F \" '{print $6}' | sed 's/automake-//g' | sed 's/.tar.gz//g' | sort -f -t . -k 1,1 -k 2,2n -k 3,3n -k 4,4n | tail -n 1)
LIBTOOL_VERSION=$(curl -fL http://ftpmirror.gnu.org/libtool | grep -E "libtool.*tar.gz" | grep -vE "sig|asc" | awk -F \" '{print $6}' | sed 's/libtool-//g' | sed 's/.tar.gz//g' | sort | tail -n 1)
