Hi Atul,

It's probably because it's just a tarball of the git source tree.  It's
easy to generate the autoconf, but would be better if we provided it with
the tarball.  Instructions should be included on how to build in
HOWTO/Install.md, here's the section on how to generate the configure
script (you'll need to export an environment variable ERL_TOP pointing to
the top of the erlang source tree).

### Building in Git ###


When building in a Git working directory you also have to have a GNU
`autoconf`

of at least version 2.59 on your system, because you need to generate the

`configure` scripts before you can start building.


The `configure` scripts are generated by invoking `./otp_build autoconf` in

the `$ERL_TOP` directory. The `configure` scripts also have to be
regenerated

when a `configure.in` or `aclocal.m4` file has been modified. Note that when

checking out a branch a `configure.in` or `aclocal.m4` file may change

content, and you may therefore have to regenerate the `configure` scripts

when checking out a branch. Regenerated `configure` scripts imply that you

have to run `configure` and build again.


> *NOTE*: Running `./otp_build autoconf` is **not** needed when building

> an unmodified version of the released source.
