Comment (by borassi):

 Did you follow the whole procedure to install igraph? In particular, you
 should do the following:

  * Download the two .tar.gz source code files [1,2] and put them in folder
 `SAGE_ROOT/upstream` (this folder is not synchronized with git).
  * run the script  `SAGE_ROOT/build/pkgs/python_igraph/spkg-src` through
 `sage -sh ./build/pkgs/python_igraph/spkg-src` from folder `SAGE_ROOT`
 (you can also run it from any other folder).

 Another possible procedure is to download the modified tarballs from [3,4]
 and put them in the folder  `SAGE_ROOT/upstream`. Then, `./sage -i
 python_igraph` should work.

 If you still have problems, could you tell me which of the two procedure
 fails, and if it still fails after running the command `sage -sh sage-fix-
 pkg-checksums`?

 Thank you very much,

 Michele
