Well, rpm-build requires perl at least on FC1 so I wouldn't be too
worried about that even though it's not necessarily too "pretty" or
"correct" ;)

On the other hand, AFAICS as a general advice, the "perl -le" thingy
above applies to non-noarch module packages only.

Generic binary backwards compatibility might hard to achieve for perl,
given that there have been some "challenges" upstream as well:
http://search.cpan.org/~nwclark/perl-5.8.3/pod/perl582delta.pod#Incompatible_Changes
And of course perl < 5.8.0 is binary incompatible with all >= 5.8.0.
