Unable to install. cannot find input file: `Makefile.in'

[biotemon]

I am trying to install IDBA in a MacOS computer. I followed the following steps:

git clone https://github.com/loneknightpy/idba.git

cd idba sudo ./build.sh

Then this is the output. Could you please point what I am doing wrong or what I need to fix the error. Thanks:

./build.sh: line 1: aclocal: command not found
aclocal.m4:21: warning: this file was generated for autoconf 2.68.
You have another version of autoconf.  It may work, but is not guaranteed to.
If you have problems, you may need to regenerate the build system entirely.
To do so, use the procedure documented by the package, typically 'autoreconf'.
