Alas, no joy.
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> gem 'flacinfo-rb'
=> true
irb(main):003:0> require 'flacinfo'
LoadError: no such file to load -- flacinfo
from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'
same result for require 'flacinfo-rb'
Weird. Last night I did a near clean install of ruby, et al. on both
machines to try and narrow down the possibilities. Didn't seem to make
a difference. My MacBook Pro doesn't care if flacinfo.rb is under
site_ruby but my destop does. ??
Thanks again for your help.
