Problem with build-dep, versioned provides

[Ville Skyttä]

apt-0.5.15lorg3.1-5.fc5, using FC5 with FE5 repository enabled, "make
srpm" in FE CVS's perl-Module-Install/devel, then:

$ sudo apt-get build-dep perl-Module-Install-0.62-2.fc6.src.rpm
Reading Package Lists... Done
Building Dependency Tree... Done
Selecting perl-Module-Build for 'perl(Module::Build)'
Selecting perl-Module-CoreList for 'perl(Module::CoreList)'
E: Build-Depends dependency for perl-Module-Install-0.62-2.fc6.src.rpm
cannot be satisfied because no available versions of package
perl(Module::ScanDeps) can satisfy version requirements

$ rpm -qRp perl-Module-Install-0.62-2.fc6.src.rpm | grep ScanDeps
perl(Module::ScanDeps) >= 0.28

$ apt-cache show perl-Module-ScanDeps | grep Provides | head -n 1
Provides: perl(Module::ScanDeps::DataFeed), perl-Module-ScanDeps =
0.60-1.fc5, perl(Module::ScanDeps) = 0.60

Oops, perl(Module::ScanDeps) = 0.60 doesn't satisfy
perl(Module::ScanDeps) >= 0.28?
