How can I install an up-to-date version of org-mode without “make” tools?
If you are using org-mode on a computer that lacks developer tools for compiling software, such as GNU Make, you will have to use a different installation method than the one outlined in the manual. Please see this thread on the mailing list for several different ways you can install a recent version of org-mode without using the customary make clean && make && make install. The result of that discussion is the file/function found in http://orgmode.org/worg/org-hacks.html#compiling-org-without-make.
