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()
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’]+’:’+
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:
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).

When I have wanted to make sure that the lib subdir of the directory
from
which the program executes is added to the load path, I use this:

make sure we can pull in anything under the directory where the

program is

being executed

$LOAD_PATH << File::join(File::dirname($0), “lib”)

seems to work for me.
