RPM dependency question - looking at the wrong directory pat

["Wang, Mary Y" <mary y wang boeing com>]

Hi,
I was trying to do rpm -ivh on a .rpm package.  However, it came back with
error:failed dependencies: perl.....  I am sure all the dependencies are
there, but it is looking at the wrong directory.  I have an older version of
perl in one directory and an newer version in another directory with all the
necessary dependencies.  I think rpm is looking at the directory of the old
perl installation.  Is there an environment variable that I can set so it
will search the dependencies in the correct directory path?  

Thanks in advance.
