Gems is not finding my id3.h file which is clearly inside of /usr/  
local/include/id3.h. When I try to install I get the following  
message:

> sudo gem install id3lib-ruby  
> Password:

1. id3lib-ruby 0.5.0 (ruby)
2. id3lib-ruby 0.5.0 (mswin32)
3. id3lib-ruby 0.4.1 (mswin32)
4. id3lib-ruby 0.4.1 (ruby)
5. Skip this gem
6. Cancel installation

ruby extconf.rb install id3lib-ruby  
checking for main() in -lstdc++… yes  
checking for main() in -lz… yes  
checking for id3.h… no  
You must have id3lib installed in order to use id3lib-ruby.  
\*\*\* extconf.rb failed \*\*\*  
Could not create Makefile due to some reason, probably lack of  
necessary libraries and/or headers. Check the mkmf.log file for more  
details. You may need configuration options.

Provided configuration options:

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/  
id3lib-ruby-0.5.0 for inspection.  
Results logged to /usr/local/lib/ruby/gems/1.8/gems/id3lib-ruby-0.5.0/

I printed out the log and I get:

yes

You could try libmtag instead.  
[http://code.google.com/p/libmtag/](http://code.google.com/p/libmtag/)

I created that project so if you have any problems I’ll be glad to help  
you.

Cheers.

I will definately check it out. I was using mp3info before id3lib but  
it was unreliable. ID3Lib produces the best results thusfar, but if  
your library works better I would be glad to use this one over any  
alternatives. I will let you know how it goes!
