Hi I am following instructions provided on installation page http://wiki.ros.org/indigo/Installation/OSX/Homebrew/Source

I am facing errors in installing dependencies for the source packages. One involves installing pcre as:

==> Downloading http://www.daemon.de/idisk/Apps/pcre++/pcre++-0.9.5.tar.gz
Already downloaded: /Library/Caches/Homebrew/pcre++-0.9.5.tar.gz
==> Patching
patching file libpcre++/pcre++.h
==> autoreconf -fvi
autoreconf: configure.in: not using Gettext
autoreconf: running: aclocal --force 
aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in'
aclocal: error: aclocal: file '/usr/local/share/aclocal/pstoedit.m4' does not exist
autoreconf: aclocal failed with exit status: 1
READ THIS: https://git.io/brew-troubleshooting

A segment of the output, which may be useful in context of autoconf. Which init file, i should add the commands as mentioned below:

==> Installing tango-icon-theme from ros/homebrew-deps
==> Installing dependencies for ros/deps/tango-icon-theme: autoconf, automake, gettext, icon-naming-utils, xz, libtool, imagemagick, intltool, pkg-config
==> Installing ros/deps/tango-icon-theme dependency: autoconf

Emacs Lisp files have been installed to:
/usr/local/share/emacs/site-lisp/

Add the following to your init file to have packages installed by
Homebrew added to your load-path:
(let ((default-directory "/usr/local/share/emacs/site-lisp/"))
  (normal-top-level-add-subdirs-to-load-path))

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

OS X provides the BSD gettext library and some software gets confused if both are in the library path.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/gettext/lib
    CPPFLAGS: -I/usr/local/opt/gettext/include

I have updated system python, but brew still try to install python. brew doctor is also not able to help much in these issues. Output of brew doctor is as follows:

     bash-3.2$ brew doctor > ~/doctor_output.txt
Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

    /usr/local/share/man/de
    /usr/local/share/man/de/man1
