[packagers] help with auto dependencies

[Christoph Maser]

Hello

i am packaging a perl tool i'd like to use (SQL::Parser) but i have a
problem with rpmbuilds dependency detection. (Centos4)

If i go straight forward i will get a package with a dependecy on
"perl(:)" because some code has "use: " inside a {} wich ist just text.

If i disable internal dependency generation i get a much smaller
dependency-set. Here is the difference:

straight forward:

With these 2 defines added:

%define __find_requires "%{__find_requires}
%define _use_internal_dependency_generator 0


Result:
----
Requires(rpmlib): rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(VersionedDependencies) <=
3.0.3-1
Requires: perl perl(Test::Differences) perl(File::Basename)
perl(Test::Exception) perl(File::Spec) perl(Class::Base)
perl(Log::Log4perl) perl(Parse::RecDescent) perl(Class::MakeMethods)
perl(Test::More) >= 0.6 perl(YAML) >= 0.39 perl-Template-Toolkit
----


So what does the internal dependency-generator actually do? how can a
use it and just remove that unwanted "perl(:)" dependency?
