ERROR with rpm_check_debug vs depsolve:
Package perl-devel needs perl(ExtUtils::Embed), this is not 
available.
Complete!


I assume that perl-ExtUtils-MakeMaker provides 
perl(ExtUtils::Embed) but doesn't declare it.

But how come the build system doesn't catch it? Is this a 
perl only problem? Or is rpm_check_debug doing something 
beyond what the build system can do?
