Heroku + Rails + GeoIp = uninitialized constant GeoIP error -

i'm trying deploy old website heroku. goes well, starts, when access through web browser get

nameerror (uninitialized constant applicantscontroller::geoip): 

i'm using rails 2.3.18 (my website simple , want deploy "as is" , asap; on dedicated server worked well).

i have geoip.dat file in 'db' folder , in controllers/applicants_controller.rb have

line 32:    geoip ||= geoip.new("db/geoip.dat") line 33:    location = geoip.country('google.com') 

if launch irb on heroku looks good:

login@sancho:~$ heroku run bash running `bash` attached terminal... up, run.7785 ~ $ irb irb(main):001:0> require 'geoip' => true irb(main):002:0> geoip ||= geoip.new("db/geoip.dat") => #<geoip:0x00000002b3a6a8 @mutex=#<mutex:0x00000002b3a680>, @flags=0, @database_type=1, @record_length=3, @file=#<file:db/geoip.dat>, @database_segments=[16776960]> irb(main):004:0> geoip.country('google.com') => #<struct geoip::country request="google.com", ip="74.125.228.110", country_code=225, country_code2="us", country_code3="usa", country_name="united states", continent_code="na"> irb(main):005:0>  

here full error log.
