Hi Dario,
In my opinion your first
'Requires: Perl'
is not needed, because you already applied the right way of require Perl with
Requires:       perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`"; echo $version))


You can take a look to specfiles of other Perl modules and take them as example (for example take a look to the source of Perl-Ace at http://koji.fedoraproject.org/koji/buildinfo?buildID=390648 )

Hello Everyone,

I created an (my first!) RPM of this software
http://www.xen-tools.org/software/xen-tools/ but I'm having some issues
when trying to install it.

Before anyone ask, yes, the long term plan is to follow all the usual
step to get the package officially accepted in Fedora, but I'd like to
have it "working" before starting to do that. :-)

So, xen-tools is just a collection of perl scripts, but having the
package I'm making depend from perl is driving me nuts! :-O Spec file is
attached (I've run it through rpmlint, and I know it have some issues,
but still...) and here's what I get when I tr to install the result of
`rpmbuild -ba xen-tools.spec':

# yum install ../RPMS/noarch/xen-tools-4.3.1-1.fc18.noarch.rpm

           Requires: perl(any)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I googled for this quite a bit, but I don't seem to be able to find
anything explaining how to make that "Requires: perl(any)" go
away... :-(

Any ideas?

Thanks a lot and Regards,
Dario
