You are right... the command was :

# gem install log4r-1.0.5.gem
....

now running this command:

# gem list --traceback gives...

ERROR: While executing gem ... (OptionParser::InvalidOption)
  invalid option: --traceback

gem version is:

# gem -v
0.7.0

???

I've got ruby 1.8.1 running on arm platform with no problems and to save
space i decided to organize external library using rubygems.
First of all i've installed rubygems 0.7.0 then i've started to install
other library using the gem command line:
  # gem -i log4r-1.0.5.gem
  # gem -i sws-0.3.gem

Did you /really/ use a -i? RubyGems 0.7.0 doesn't allow that option
anymore. It should have been ...

    # gem install log4r-1.0.5.gem

If you did use a -i, then we might have conflicting versions of gem loaded

Everything installed succesfully but

any command i issue to test the installed package, i get this error:

# gem list
*** LOCAL GEMS ***
ERROR: While executing gem ... (NoMethodError)
undefined method 'loaded_from=' for nil::NilClass

Try this with the --traceback option. This will give us a stack dump. E.g.

  gem list --traceback

Thanks.

Good. I was worried about a version mismatch.

now running this command:

# gem list --traceback gives...

ERROR: While executing gem ... (OptionParser::InvalidOption)

Oops. That was my fault. I was working from memory instead of checking
the docs.

The option is --backtrace. Please try it again.

Sorry for the confusion.
