Filtering excessive requires

[Adam Huffman]

I'm trying to build perl-Bio-SamTools for EPEL5.  As part of this, I
need an EPEL build of perl-bioperl and its associated dependencies.

One problem I've run into is that the Fedora .spec for perl-SOAP-Lite
uses the filtering macros available in >F11 to remove some unwanted
Requires entries, generated by the automatic dependency scanning.

Is there an approved way of recreating that functionality for EPEL5?

The methods suggested on https://fedoraproject.org/wiki/Packaging/Perl
haven't worked so far.
