Slight snag. This package was put together by someone who doesn't 
actually understand what they are doing. They have got round the 
clashing file problems by putting it into the "vendorperl" instead of 
"perl" tree. But the "perl" tree is earlier in @INC than "vendorperl".

So the nice new version you just installed isn't actually used at all.

To prove it to yourself...
Try editing the code in the file (e.g. put a syntax error in it), and 
then run this command. It should fail as there is a syntax error in which is where the perl-IO rpm is installed.
    perl -MIO -e 'print $IO::VERSION;'
You'll find it still works perfectly, as it isn't using the version you 
just installed from


If it was that easy, I would have done it years ago :-)
