Yet it compiles fine on a system with the following specs:

Not all is lost though. I happen to have g++-4.8 installed on all my systems as well, so I set the line:
'base_env['CXX'] = "g++"' to 'base_env['CXX'] = "g++-4.8"' and it seems to have compiled, though with a lot more warnings.

This (https://www.mail-archive.com/darktable-devel@lists.sourceforge.net/msg04714.html) seems to be a similar issue.
Not all is lost though. I happen to have g++-4.8 installed on all my systems as well, so I set the line: 'base_env['CXX'] = "g++"' to 'base_env['CXX'] = "g++-4.8"' and it seems to have compiled, though with a lot more warnings.
EDIT: Using g++-4.8 does seem to do the trick.
