autom4te (autoconf-2.57-3) broken?

[Dean Takemori]

Has anyone run into this for Yellowdog 3.0 + errata?

I believe some perl IO stuff changed between perl 5.6 to 5.8, but to 
the point of
breaking autoconf due to missing IO::File??  Something's fishy about 
this, but I'm
not sure what's wrong.

Is IO/File.pm not in the standard perl rpm?  If not, where is it, and 
why?  It's an odd
omission.  Is autoconf-2.57-3 broken w/r.t. perl 5.8?  What's the fix?

Thanks for any hints/clues
