net-libs/rb_libtorrent does not compile.
It stops with errors:

Finally it compiles with USE="-examples" so something is wrong
It might also be the case with earlier versions. I updates from net-libs/rb_libtorrent-0.16.17-r2 and haven't tried all in between versions.

Latest version also fails to compile but this is really a problem you should report to the upstream project. could you do that please?

[Comment 2 Kees Bergwerf 2015-09-06 23:12:56 UTC]

I was away from home for two weeks, but now I could see for myself that 1.0.6 still does not build with use=examples

So I reported it to [e-mail] and all I can do is wait... :-)

Thanks. Would it be better to open a bug here instead? https://github.com/arvidn/libtorrent/

[Comment 4 Kees Bergwerf 2015-09-12 12:52:55 UTC]

Ok I hope I did it right: https://github.com/arvidn/libtorrent/issues/157

Yes that looks good to me thanks.

Fixed upstream and I backported the patches to the 1.0.6 ebuild. Thanks for the report!
