#129 perl-AutoClass conflict

[boxman]

The packages perl-Class-AutoClass (biopackages) and perl-AutoClass (which is an extras package) conflict. Bioperl (bp) requires perl-Class-AutoClass. But, perl-Class-AutoClass conflicts with perl-AutoClass on FC5. So there needs to be a revision of the spec.in's that depend on these packages, such that, an
%ifdistro is added so the requires is perl-AutoClass on FC5 and perl-Class-AutoClass elsewhere.
