Whatweb update died

Today when I check routine update, whatweb has an update form 0.4.7 to 0.4.8.
After the update, I got an error when running it:

Code:

---

I tried adding rchardet by gem install rchardet and it doesn't work.
Changing to ruby 1.8 gives me another error:

Code:

---

root@vulman-bt5r1:/pentest/enumeration/web/whatweb# ./whatweb

Is there a fix for this?

From what I've read, Whatweb 0.4.8 is still under development.

ouch, I was freaking out about my messed up ruby, lately I blame everything to ruby (inside joke).
Good to know it's under development.

So I should get 0.4.7 back, right? I downloaded 0.4.7 from the developer's website, but when I tried to run, I still got the following error:

Code:

I guess I have something wrong with my ruby? Is there any advice for a fix?

my 0.4.8 works "perfectly" with no modifications; from either maxfx's bt5up or sickness bt5 updater.

id suggest going that route than manually breaking other things...

Personally I rollback all the tools depending on Ruby192, it's way too buggy, also died about a month ago. In synaptic, just click on "package" then "force version", then a window will pop up with the available versions. So you can install your previous version, I did that after beEF required ruby1.9.2 , so I went back to the older working version supporting ruby1.8.0, a more stable version. Bug #361 refers that exact output. I was looking around and they are working on it, probably will be fix it for the bt5r2. And there are few sweet tools :)

Thank you for your advice. :)
