Subject: changing the environment for current process

I have the following situation:
I require an additional library, not part of the current search path.
I have done that simply by:
$:.push(<path>)
and that would work fine if I would not need shared libs. I tried
to simply set
ENV['LD_LIBRARY_PATH'] = ENV['LD_LIBRAY_PATH']+':'+<so-path>
but that seems not to work, the shared library is not found. 
It only works when I make an
setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:<so-path> 
before I start the script. Is there a way to modify the 
environment for the current ruby process?
I would like to have the possibilites usually enabled by
module ( a tool where the environment can be altered with , where no ruby
support seems to exist).

Regards,
Tammo
