Sage's CHomP interface is out of date: the executables now have different names and may use a different syntax. Also, CHomP has not been updated recently — the most recent changes at https://github.com/marciogameiro/CHomP (see also http://chomp.rutgers.edu/software.html) are 5 years ago — and it doesn't build on OS X. I'm not sure about other platforms. It used to be the case that CHomP was necessary for certain calculations, such as finding generators of homology groups, but Sage can now do all of that on its own. So let's deprecate the CHomP interface to Sage.
