[Nix-dev] Error in travis that I can't reproduce on my system

[Andreas Herrmann]

Hi,

I'm working on a PR[1] to add the blitz++ library[2] to Nixpkgs. However, I'm baffled by an error that travis produces [2, line 822]. The package builds fine on my Nix in openSUSE as well as on NixOs in a virtualbox. It seems to be some issue with autotools where the configure script puts a literal `no` into a `#define` that should just be left empty if the feature is not available.

Any ideas how I could fix this? Is there something different about the tool-chain used on travis?

Best, Andreas
