I suspect that Apple's perl is 5.8.8 and it is installed in /usr/bin. It needs to stay there because Apple's updates may depend on it. Installing 5.10.1 in /usr/bin/ replacing 5.8.8 is not recommended.

I also suspect that perl 5.10 is installed in /usr/local/bin but that might be different like /opt/bin depending on just how you installed it.. Look around for it. /opt/local/lib/ sounds unlikely to me.

You are probably going to make a change to your PATH environment variable to make the directory that perl 5,10 resides in appear before /usr/bin.

A shell command like: 
setenv PATH /usr/local/bin:$PATH  # csh

PATH=/usr/local/bin:$PATH   # something like this in bash
export PATH

You can also specify PATH in a startup file
$HOME/.MacOSX/environment.plist.
but you'll have to create that including the .MacOSX directory unless it's already there. There are some instructions on Apple's web site. Ask if you'd like a sample.

@INC is a perl array that lists directories in which modules can be found. There are a bunch of standard locations relative to the directory that perl itself lives in but you can add more directories by setting the PERL5LIB environment variable to a PATH-like list of other directories. That too can be done in environment.plist.

It's a bit hard to understand why iplayer doesn't have an installation script or at least some less geeky instructions for users.
