i did emerge the latest ruby a couple of days ago.  just restarted 
apache today for some config changes to take effect, and that's when i 
notied my mod-ruby setup was busted.

looking through the main apache error log, i just found this error:

"mod_ruby: failed to require apache/eruby-run"
"mod_ruby: error in ruby\n/usr/lib/ruby/1.8/apache/eruby-run.rb:45:in 
`require': No such file to load -- eruby (LoadError)\n\tfrom 
/usr/lib/ruby/1.8/apache/eruby-run.rb:45\n"

--- /usr/lib/ruby/1.8/apache/eruby-run.rb:45:
require "eruby"
---

i assume that it's looking for eruby.so, which is in 
/usr/lib/ruby/1.8/i686-linux-gnu.  i've symlinked to that file in 
1.8/apache:

eruby.so -> /usr/lib/ruby/1.8/i686-linux-gnu/eruby.so

but still no joy.  at this point i'm wondering if the mod-ruby ebuild is 
wonky or if it's a problem with the .so being in a directory that's not 
in the right path?  symlinking 1.8/apache into site_ruby/1.8 doesn't 
work either, but changes the error message in my apache error_log:

"error in ruby\n/usr/lib/ruby/site_ruby/1.8/apache/eruby-run.rb:45:in 
`require': No such file to load -- eruby (LoadError)\n\tfrom 
/usr/lib/ruby/site_ruby/1.8/apache/eruby-run.rb:45\n"

[ note path change from 1.8/ to site_ruby/1.8 ]

so it appears that require prefers site_ruby/1.8 over 1.8?  but still no 
explanation why the fatal on the require "eruby" statement on line 45 of 
eruby-run.rb.
