           Summary: cpanspec error: Dest dir longer than base dir is not
                    supported
           Product: Fedora

Description of problem:
I am trying to build some CPAN modules as RPMs (namely Env::C and
IO::Socket::Multicast), but the build fails with the following error:

[...]
extracting debug info from
/root/rpmbuild/BUILDROOT/perl-Env-C-0.08-1.fc16.x86_64/usr/lib64/perl5/vendor_perl/auto/Env/C/C.so
Dest dir longer than base dir is not supported
error: Bad exit status from /var/tmp/rpm-tmp.LI9AHv (%install)

I am not sure why the length of both paths should matter at all, but the cause
of the problem is that cpanspec sets up too long buildroot.
Taking the generated spec file, shortening the buildroot path, and rebuilding
the package using the modified spec file works for me

Before:
BuildRoot:      %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n)
After:
BuildRoot:      %{_tmppath}/%{name}

Version-Release number of selected component (if applicable):
cpanspec-1.78-9.fc16.noarch

How reproducible:
100 %


Steps to Reproduce:
1. cpanspec --build Env::C

Actual results:
build fails with the above error message

Expected results:
perl-Env-C binary and source RPMs should be built
