Problem overview (details below):
I'm having an apache2 + ruby integration problem when trying to connect to an ODBC data source. The main problem boils down to the fact that scripts that run fine from an interactive shell crash ruby on the database connect line when run as a cgi from apache2. Ruby cgi's that don't try to
access the ODBC datasource work fine. And (again) ruby scripts that connect to a database with ODBC do fine when executed from the command line (or cron). This behavior is identical when I use perl instead of ruby.
So, the issue seems to be with the environment provided for ruby (perl) by apache2, but I can't figure out what is wrong or what to do about it.
Does anyone have any suggestions on how to get these cgi scripts to work properly?
I've tried many different things to get this to work, and I'm happy to provide more detail of any aspect if that will help.

) a minimal version of a script (anonymized) that will crash in apache but run successfully from a shell:
#!/usr/bin/ruby
require 'cgi'
require 'odbc'
cgi = CGI.new("html3")
aConnection = ODBC::connect('DBFile', "username", 'password')
aQuery = aConnection.prepare("SELECT zzz_kP_ID FROM DBTable WHERE zzz_kP_ID = 81044")
aQuery.execute
aRecord = aQuery.fetch_hash.inspect
aQuery.drop
aConnection.disconnect
# aRecord = '{"zzz_kP_ID"=>81044.0}'
cgi.out{
cgi.html{
cgi.body{
"<pre>Primary Key: #{aRecord}</pre>"
}
}
}
