Yeah, I tried that too. The load succeeds but then the methods fail:
Should work like this:

irb(main):001:0> require 'flacinfo'
=> true
irb(main):002:0> song = FlacInfo.new("dread.flac")
=> #<FlacInfo:0x19208 (STREAMINFO size=34 offset=8) (SEEKTABLE size=486
offset=46) (VORBIS_COMMENT size=235 offset=536) (PADDING size=4065
offset=775)>
irb(main):003:0> song.print_tags
ARTIST: 10cc
TRACKNUMBER: 01
DATE: 1978
vendor_tag: reference libFLAC 1.1.2 20050205
ALBUM: Bloody Tourists
TOTALTRACKS: 13
TITLE: Dreadlock Holiday
YEAR: 1978
GENRE: Rock
offset: 536
block_size: 235
COMMENT: High Quality, EAC secure, Lossless flac 
=> nil

But instead I get:

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> gem 'flacinfo-rb'
=> true
irb(main):003:0> song = FlacInfo.new("dread.flac")
NameError: uninitialized constant FlacInfo
        from (irb):3
