what & where is this file --- ltmain.sh

[allan George]

Hi,

what & where is this file --- ltmain.sh ? It is hiding actual libtool installed ? 

i have installed 2.4.2 version for libtool :---

ftp://ftp.gnu.org/gnu/libtool/libtool-2.4.2.tar.gz

After installing 2.4.2 version of libtool, If i run whereis command, i get following output :----

/pi/libtool-2.4.2$ whereis libtool

libtool: /usr/local/bin/libtool

But if i run libtool --version:---

/home/pi$ libtool --version

ltmain.sh (GNU libtool) 1.5.26 (1.1220.2.492 2008/01/30 06:40:56)

Why libtool --version command is not showing the latest installed version of libtool 2.4.2?

Please suggest.
