F16 how to install "less" ruby gem?

[Michał Piotrowski]

Hi,

I want to install "less" gem. I switched to root account, and typed

# gem install less
Fetching: therubyracer-0.9.10.gem (100%)
Building native extensions.  This could take a while...

...

And it's all - install process stops. When I check what is happening
with ps I get

ps -aux :

It seems that as is in zombie state. Could anyone advise where to
start looking for the solution to this problem?
Where it can be a problem? Gem itself or toolchain?

The problem will be the gem and its dependencies probably. Since the 
therubyracer gem bundles v8 javascript engine, it may take some time to 
compile. The /ext directory of the therubyracer gem might be of interest 
to you.

However, since this is nice example of bundling, I would suggest you to 
take a look for some alternative to less gem.

I'll try to build it manually - without gem scripts.

I need lessc with --compress option to build bootstrap framework. I'm
not sure if "less" gem is appropriate for this task, but I wanted to
try it.

The canonical version of lessc is written for node.js.  Looks like the
ruby gem just runs that through some sort of node/v8 interpreter for
Ruby.  It's probably a lot easier just to run it through node itself.

I build node packages personally for now until I can whip it into
shape for Fedora (which will be F18 or Node v0.8, whichever comes
last.  I have patches for the 0.7 development branch almost ready to
send upstream :-):
http://nodejs.tchol.org/

Enable the repository, then just `yum install nodejs-compat-symlinks
npm` and `npm install -g less`.

(You can also rebuild the SRPMs if you don't trust me, but then you
still have the whole "building V8" problem. ;-)

Actually it would be nice if less could use execjs gem, which choose 
whatever JS engine is available on your platform. But unfortunately, 
less gem has hardcoded dependency for V8.

Thank you very much - this is exactly what I needed :)
