[Nix-dev] x264 snapshot expression, is it the expression or the makefile please?

In general you can use "-K" to nix-env or nix-build, and the temp
directory won't be deleted after an unsuccesful build.
There you will have a file called "env-vars", which you can source in
bash, and have the same building environment as the setup scrip had.
Then you can interactively try to understand what happens.

Regards,
Lluís.
