Subject: Re: db2_connect on ruby 1.8.5 rubygems 1.3.5

IMHO upgrading to a more current Ruby is your best bet

However, if that's not possible you could specify an older version of
the ibm_db gem that aligns with the version of Ruby you have
Looks like Ruby 1.8.5 was last updated in 2008, so maybe ibm_db 0.9.3
- 1.0.1 will work

cheers
