Debugging bad gems?

ruby-talk

Hey folks,

I've installed two gems from http://www.textualize.com -- sruby (
http://www.textualize.com/sruby\) and ruby-marc (
http://www.textualize.com/ruby_marc\) via gem install from rubygems.org to my
ruby 1.8 install on x86 Debian unstable. Both gems installed correctly as
far as I could tell, and I've installed many other gems that worked just
dandy. However, neither of these two gems work. For sruby I get the
following in irb:

require 'sru'

LoadError: no such file to load -- sru
        from (irb):1:in `require'
        from (irb):1

The marc gem does require correctly, but when it comes time to execute the
sample code listed I get the following error from irb:

    reader = MARC::Reader.new('batch.dat')

NameError: uninitialized constant MARC::Reader
        from (irb):2

Any ideas on how to debug this, or should I just badger the folks at
textualize.com?

The fact that there is no reference to RubyGem's custom_require in your
backtrace leads me to suspect that you don't have RubyGems loaded. Put
an explicit "require 'rubygems'" in the code, use the -rubygems switch
on the command line, or set the RUBYOPT environment variable to
'rubygems'.

Don't know about this, but I would double check the RubyGems issue first
before pursuing other options.

Did require 'rubygems' in irb -- now require 'sru' returns false instead of
choking like it did earlier. Still doesn't work though, natch. MARC fails
in the same way. Weirdness.
