[Clockwork]

Hi,
when i use:
gem install nokogiri
i get following error in mkmf.log:
 /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crti.o: unrecognized relocation (0x2a) in section `.init'
/usr/bin/ld: final link failed: Bad value

I don't think this is a nokogiri-specific problem, but a problem with the libc on your system.

I googled and found this:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808205

Can you compile other C extensions? What happens if you run `gem install bcrypt`?

After Updating my system today, the error dont appear anymore. It worked fine!
