On a fresh install of Kubuntu Linux (ver. 8.04.01), I'm not having good day trying to get ruby and rubygems back and functional.
The Ruby-lang. website recommends using the package manager to install ruby, so I did that.
Then I installed rubygems 1.8 from the rubyforge tarball. I then installed several gems successfully, but the one I really had to have - webby - wouldn't install. I've not have this problem before, so it doesn't seem likely that it's a webby problem.
I didn't know how to uninstall the rubygems 1.8 install. I simply went to the adept package manager and installed rubygems from that.
But webby still won't install:

On the webby list, it was suggested that I install ruby from source.
Is that really the best idea? I developed modest pascal programs from my own source code, years ago, but I have no idea how to compile ruby for what I presume is C source, on Kubuntu.
What should I do? If going from source is the best idea, can anyone point me to a resource which will bring me up to speed on how to do this? (I'm looking for this resource, and may find it, but suggestions are certainly welcome.)
Thanks!

I got webby installed under Ubuntu 8.04 without having to compile
anything from source. I did face some other issues, though - see
[http://markmail.org/message/apqjib2ftfr5dukk](http://markmail.org/message/apqjib2ftfr5dukk)
Since your immediate problem appears to be pthreads-related, see if
you have the following installed:
libpthread-stubs0
libpthread-stubs0-dev

Here's what's installed, apparently -
$ locate libpthread
/lib/libpthread-2.7.so
/lib/libpthread.so.0
/lib/tls/i686/cmov/libpthread-2.7.so
/lib/tls/i686/cmov/libpthread.so.0
So, I went to Adept and found the two things (packages? modules? I haven't a clue) an installed them.
Then...
$ sudo gem install webby
[sudo] password for tomc:
Building native extensions. This could take a while...

This was what was happening before.

On ubuntu, to compile anything, you should install the build-essential package:
$ sudo apt-get install build-essential
You may also have to install the ruby1.8-dev package as well:
$ sudo apt-get install ruby1.8-dev
Good luck. When compiling gems, you usually will need dev version of any library that the gem has a dependency on.

Thanks, Doug. I'll probably give this a try. Since what I have now isn't working too well. New adventures in Ruby/Kubuntu, for the ever hopeful, and increasingly desperate! ~t.

Tom,
I've never compiled ruby, or much of anything, for ubuntu
specifically, but I've had to build modern ruby package for work since
some of our boxes run (very very very) old versions of linux, and I've
had to build ruby for my irix box since there are no stock packages of
it. It's not the \_most\_ straight forward build, but it's still pretty
easy. Take it slow, and read that little README in the tarball, it
tells you everything.
You've got very little to worry about!

On a belated note I still wonder if anyone has managed to
compily ruby statically and made it work. When I dig into which
extensions I want to add, it is openssl or something else that
seems to "act up" ☹

I'm happy to report that the help of Michael Guterl, of the Webby list, I've just successfully compiled Ruby from source (with added libraries/extensions/ or whatever they were: zlib1g-dev / libreadline5-dev / openssl) installed it, then installed Rubygems (which had been giving me real headaches), and then webby.
Haven't used it yet, but this is the farthest I've gotten on this in 4 days. The Kubuntu packages weren't installing well for me. This solved the problem (so far).
Now I'm off to go study what I just did. Couldn't have done it without Michael's patient and expert coaching. I have the complete list of commands required if anyone wants them.
