I am trying to install some version of libxslt-ruby on my CentOS 4.7  
Linux system, and I am getting this error:

My version of ruby is the stock version for CentOS 4.7:

I’ve narrowed things down to a problem with mkmf.rb – it is missing a  
method named find\_header. I don’t really know ruby, but if someone can  
send me a suitable code fragment, I can certainly patch mkmf.rb. I just  
want to get ‘spock’ ([http://hyperstruct.net/projects/spock](http://hyperstruct.net/projects/spock)) functioning.

Well, the latest is available at  
[http://svn.ruby-lang.org/repos/ruby/branches/ruby\_1\_8/lib/mkmf.rb](http://svn.ruby-lang.org/repos/ruby/branches/ruby_1_8/lib/mkmf.rb)

However, I found all sorts of things didn’t work with 1.8.1 (which is  
really ancient), so under RHEL 4 I moved to the 1.8.5 packages from the  
CentOS testing repository:  
[http://dev.centos.org/centos/4/testing/i386/RPMS/](http://dev.centos.org/centos/4/testing/i386/RPMS/)  
and everything was fine. If at all possible in your situation, I’d  
strongly recommend it.

Regards,

Brian.

P.S. To get even more up-to-date, you could consider rebuilding the  
RHEL5 or Fedora packages for CentOS 4. You need to change one line in  
the .spec file (dependency on libX11-devel needs to be changed to  
xorg-x11-devel)

It still does not work:

/usr/local/share/bard-spock/spock update.rdf -i  
removed\_email\_address@domain.invalid -d ~/.mozilla/mccoy/08c43j81.default/

I upgraded to the ruby-1.8.5 pavkages from the centos 4 testing repo,  
downloaded and did a ‘gem install’ of libxml-ruby and libxslt-ruby:

What do I need to do now???

All I really want to do is sign a couple of FF3 Toolbar extensions in  
a Makefile using a pure CLI command, and not have to manually sign them  
with a pointy-clicky tool!

I may end up re-writing this spock tool in Tcl.

It is not my code. I guess I will need to ‘blindly’ hack  
normalize\_update\_rdf.rb…

Have you done ‘require “rubygems”’ ?

I’m not familiar with libxslt at all. Check you have  
/usr/lib/ruby/gems/1.8/gems//lib/xml/libxslt.rb

It is used by the ‘spock’ program, which is written in Ruby as a CLI  
‘hack’ that allowed the author (of spock) to sign his nightly built  
packages (built on a headless server). FF3 extensions use an XML file  
(update.rdf) and libxslt is used to parse this file as part of the  
process of ‘signing’ it (computing a signature from the file’s contents  
and a private key (the public key is in the installer file,  
install.rdf). This is so FF3 can verify that the update.rdf is  
ligitimate.

The Mozilla Dev crew have this xulrunner application, mccoy, which is a  
GUI application for creating key pairs and for signing FF3 extensions.  
It is not something that is useful for people who use make and/or  
other automated build processes (like ant), esp. not on unattended build  
servers.

One of the comments on the spock blog says:

Maybe that will help?

How exactly does libxslt help you do this?

Sort of. I needed additional munging around with links to make the  
spock code happy (it seems to have a different idea of where and what  
ruby-xslt installs than what either the libxslt-ruby gem or the  
ruby-xslt tarball, although the ruby-xslt tarball came closer).
