Gem dependency (Hpricot)

Hi,

This is from Hpricot’s install page:

If you’d prefer not to use RubyGems, you can also acquire a plain Ruby
distribution: http://code.whytheluckystiff.net/dist/hpricot-0.4.tgz

However, if you download, and try to build with rake, you get:
bever:/usr/src/ruby/hpricot-0.4> rake
(in /home/source/src/ruby/hpricot-0.4)
rake aborted!
no such file to load – rubygems
/home/source/src/ruby/hpricot-0.4/Rakefile:3:in `require’
(See full trace by running task with --trace)

So not preferring to use gems doesn’t really buy you much.

PS I’m sending this to this list because Hpricot is not alone in this.
Dependencies on gem are not good. Of course I’ll give in, install gem,
and subsequent dependencies will go unnoticed here, until I try to run
something on a different computer.

Oh, I’m sorry, there should be a setup.rb in there. I’ve just updated
the file
give it a try again. The installation commands is just ruby setup.rb.

Thanks. It doesn’t seem to be in SVN though, which is what I use.
It’s no big deal, and I’m very enthioustastic about Hpricot.
Before this I experimented with htree, to_rexml and xpath, but this
combo was to slow to be workable.
The README file, by the way, ends rather abrubtly.

I think that most projects whose Rakefile depends on Gems do so because
they need Gem::Specification for the Rake GemPackageTask. Generally I
tend to leave out an explicit require and do something like:

Oops, I meant explicit dependency (in gems) rather than explicit
require.

tend
to leave out an explicit require and do something like:

require ‘rubygems’ rescue nil

… later:

if ! defined?(Gem)
warn “Package Target requires RubyGEMs”
else
spec = Gem::Specification.new do |s|

end
