Installing emacs 25 under RHEL6

The newer versions of emacs include JavaScript and other user modes useful for modern app development:

$ git clone git:// $ sudo yum groupinstall "Development Tools" $ wget $ tar jxvf autoconf-2.68.tar.bz2 $ cd autoconf-2.68 $ ./configure; make; sudo make install $ sudo yum install texinfo libXpm-devel giflib-devel libtiff-devel libotf-devel $ cd ../emacs $ make bootstrap; sudo make install

This process can take upwards of 20-30 minutes.
