Comment (by ncohen):
Hello,
> What do you mean by 'fake' .tar.gz archive?
Sigh.... After some debugging, it seems that if I click on "source code"
at this address (http://igraph.org/c/#downloads) I get a file like that:
{{{
~$ file igraph-0.7.1.tar.gz
igraph-0.7.1.tar.gz: POSIX tar archive
}}}
If I copy/paste the url and download it with wget I get a file like that:
{{{
~$ file igraph-0.7.1.tar.gz
igraph-0.7.1.tar.gz: gzip compressed data, last modified: Tue Apr 22
19:55:20 2014, max compression, from Unix
}}}
Anyway. It works, sorry for the misunderstanding.
> So I believe it is GPLv2. However, it does not seem to be a problem:
http://www.gnu.org/licenses/gpl-faq.en.html#WhatDoesCompatMean. Moreover,
also package latte_int is distributed with Sage with GPLv2.
Yes yes you are right. It would have been a problem for a standard
package, but of course not for an optional one.
> In order to solve this problem, I have added a check in the spkg-install
script, and I had to modify the sage-spkg file to allow an error which
depends on the user. Do you agree with this modification?
Oh. Well, I did not want to say that it had to be modified on our side. I
merely wanted to tell you what had happened and that it had been reported
upstream. For me it is not a very important problem, and for as long as
upstream knows and fixes it I do not think that we should care `O_o`
