Libtool library used but `LIBTOOL' is undefined

Libtool library used but `LIBTOOL' is undefined

I attempted to install this tool, glb in CentOS 6.5
https://github.com/codership/glb

Traditional Linux Source Build often have configure, make files available.
But this software was not having any such files. One shell script named
bootstrap.sh was available. When I run the script, I was struck up with this error.

Libtool library used but `LIBTOOL' is undefined

Searching thro forums I came across this link.

http://stackoverflow.com/questions/18978252/error-libtool-library-used-but-libtool-is-undefined

So Here they suggested to run
autoreconf
aclocal -I /usr/share/libtool
aclocal -I .

Again that did not solved.
Finally it was suggested to run libtoolize command from current directory.
But that command was not available; also I was not able to find the name of the package.

This link,

http://wiki.apache.org/couchdb/Installing_on_Fedora10

suggested to install a package titled libtool

yum install libtool

After this step, libtoolize command was available.
After which I issued

libtoolize
aclocal
autoheader
autoreconf
./bootstrap.sh

The above steps generated configure file automatically.
