Rails - May 2006 - Problem with ''require xmlsimple'' in vendor code

Hi there

I''m trying to "require ''xmlsimple''" in some
code that lives in vendor/

I''ve installed the xml-simple gem, and can confirm this at the command
line
with ''gem  list --local'' which shows I have v.1.0.8 of the
gem.

However, when I start up lighttpd I get this:

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in
`require__'': No
such file to load -- xmlsimple (MissingSourceFile)

I''ve tried adding in "require ''rubygems''"
before the "require ''xmlsimple''"
but to no avail.

The file that requires the xmlsimple gem lives in
vendor/payment-1.0.1a/lib/payment
which is a hacked version of the Payment credi card processing module so
that it works with another gateway.

My dispatcg.fcgi has this line: require File.dirname(__FILE__) +
"/../config/environment"

but am not sure if this relevant.

I''ve also added the following line to config/environment.rb:

 config.load_paths += %W( #{RAILS_ROOT}/vendor/payment-1.0.1a/lib )

Any clues would be greatly appreciated.
