Gem program -- cannot install libxslt-ruby-0.3.6.gem

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

sauron.deepsoft.com% sudo gem install libxslt-ruby-0.3.6.gem
Password:
Building native extensions. This could take a while…
extconf.rb:58: undefined method `find_header’ for main:Object

ERROR: Error installing gem libxslt-ruby-0.3.6.gem[.gem]: ERROR: Failed

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) functioning.

Well, the latest is available at
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/
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
[email protected] -d ~/.mozilla/mccoy/08c43j81.default/

update.rdf.signed

from /usr/local/share/bard-spock/spock:53

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

How exactly does libxslt help you do this?

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:

Instructions how to get it work on FC8. …
You have to download http://gregoire.lejeune.free.fr/ruby-xslt_0.9.3.tar.gz
Follow instructions there (ruby extconf.rb; make; make doc; make install)
This will leave xslt.rb in /usr/lib/ruby/site_ruby/1.8/xml/xslt.rb

Apparently, Ruby needs libxslt.rb there, so do:
sudo mv /usr/lib/ruby/site_ruby/1.8/xml/xslt.rb
/usr/lib/ruby/site_ruby/1.8/xml/libxslt.rb

Subsequently, spock runs.

Maybe that will help?

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).
