I am trying to build a cross-compiler for my Raspberry Pi to ultimately compile ffmpeg for it and I am following this tutorial.

After having configured ct-ng and upon calling nt-cg build it fails and prints this:

[INFO ]  Performing some trivial sanity checks
[INFO ]  Build started 20150217.180740
[INFO ]  Building environment variables

[INFO ]  Retrieving needed toolchain components' tarballs
[ERROR]    Could not retrieve 'cloog-ppl-0.15.10'.
[00:31] / make: *** [build] Error 1

Taking a look into the build.log I find

Manually trying to fetch the file seems not to work because it is not available(?)

I have actually compiled the newest CLooG but I don't know how to point nt-cg in the right direction.

Any help would be appreciated.
