New users login problems / digest::md5

I’ve determined from (perldoc perlocal) that I have digest::md5 version 2.16
installed. I’m wondering if this mod has issues that would create my login
problems with new users and changing passwords. I’m also not sure why I
can’t install a new version of the mod (if in fact this version is
problematic)…

any thoughts?

thanks in advance.
